TWO RARE ORIGINALS have been listed, both are 1913. If you want all the various nameplates, be sure to look at them!

We have added a web page describibg the B-type nameplates. These interesting plates present many puzzles. See this page for this useful collector reference.

You are free to copy or reference any of the material, text and photos, presented on this page for non-commercial collector use. Credit given to Tom French W1IMQ would be appreciated.

I am always happy to answer questions, but if you attach photos to your email, please keep them reasonably sized. I suggest that you set your camera resolution to take email-sized photos (typically about 1024 pixels wide, see your camera instructions); you will find that your correspondents appreciate this. An alternative is to use your picture program to shrink them to a width between 800 to 1000 pixels before sending them.

All foreign shipments are at buyer's risk. This should not concern most buyers, since I ship by priority airmail which is tracked. I have never had a problem with shipments to most countries, including Italy, Germany, Australia (although one package went via Brazil !), Japan, and many others. Priority mail usually includes up to $70 - $80 of insurance automatically. Full insurance is available for shipments to most countries (average cost $6.00), although many buyers choose to forgo it and assume the risk.

WELCOME to our website offering vintage Vibroplex telegraph instruments and accessories. I have been selling telegraph reference books, keys, and other instruments to collectors for over 20 years, as Artifax Books. Since one of our specialties -- the sale of older Vibroplex items -- took on a life of its own, we decided it deserved its own website. Here you will find all of our Vibroplex offerings.

For other telegraph and communications books, CDs and instruments, see the original Artifax Books website.

Let me know if you will be mailing payment and I will hold the item for you. For foreign payments, see the announcements.

EMAIL and QUESTIONS: My email address is .

SHIPPING OF BUGS: I will usually remove at least the weights, paddle and knob from the key and pack them separately in the box. (If the paddle is left on the key, it is often broken in transit.) I may remove the entire lever/pendulum assembly, especially on older bugs where the paddle/knob cannot be easily removed; see this page). In this case your task would be to re-install lever onto the pivots, afix the dot lever sping to its adjustment screw, and make the appropriate operating adjustments. Feel free to ask if you have any questions or concerns.

********** A BRIEF HISTORY **********

First there was Horace Martin's "Autoplex," an electromechanical semi-automatic telegraph key. Then in 1905 came his Vibroplex key, a manual bug. Today, thousands of keys and many models later, the Vibroplex key is a collecting specialty in itself. This page will include anything Martin or Vibroplex related.

You will occasionally see statements that the Vibroplex was first produced in 1904. There is no evidence for this. It is based on the "Aug 9 1904" patent date on the first nameplates - but that patent was for a release-mechanism bug, not for the Vibroplex (which patent was finally applied for in April 1906). See pages 37 - 38 of the Vibroplex Collector's Guide, third edition. The earliest ad offering the Vibroplex for sale is in the March 1905 issue of "The Railroad Telegrapher" at page suppl. 16 (this ad was discovered by Fabio Bonucci, IK0IXI, NB1V).

THE GEORGIA BUGS: Two years after starting production of the Vibroplex in New York, Martin moved to Georgia for 1907-08. First he produced a few keys in Norcross under United Electrical Manufacturing Company, then a few more in Atlanta under Martin Manufacturing Company.
The Norcross plates are found in a small size (2-1/4" wide) and a large size (3" wide); the wording is identical (with the incorrect last patent number 342,154 which should be 842,154).

After Horace Martin developed his Vibroplex, others were quick to copy it. Around 1911 to 1915 J.E. Albright, Martin's "sole selling agent," threatened to prosecute not only those manufacturers but anyone who used the "bastard bugs" - unless the operator paid a $2 license fee. Bugs bearing the Albright license nameplate are especially collectible Vibroplex artifacts and will be included on this page (in the rare event we have one for sale).

Additional information on specific models may be found under the models for sale headings below. For much more information on the history of the company itself, see Randy Cole's Vibroplex Collectors website, the book by Bill Holly (K1BH), The Vibroplex Co. Inc., which is available from The Vibroplex Company, and John Casale's (W2NI) web pages on Horace G. Martin. And be sure to sign in at Fabio's Vibroplex Collector's Association.

********* THE B-TYPE NAMEPLATES *********

The most interesting era in the production of Vibroplex keys was, to me, those years following Horace Martin's return to New York from Georgia. This encompasses the use of the B type nameplate: 1910 to 1916. Within this brief period, Martin used six different legends on his nameplates, two of which are the rarest known. Go to this page where we describe the various B type nameplates and the keys on which they are usually found.

********* THE CHROME BASED BUGS *********

While the chrome base is usually associated with the DeLuxe models (jeweled pivot, red paddle and knob), it actually replaced the optional nickel finish before the DeLuxe bugs were offered. We recently sold a 1938 Lightning Bug with a chrome base; this was a pre-DeLuxe model.
Once the DeLuxe models were offered (in 1939), chrome would be available only on those.

********* THE EARLY DELUXE MODELS *********

The Deluxe bugs are identified by their chrome base, red paddle and knob, jeweled upper and lower pivots, and (since the jewels are insulating glass) a grounding pigtail from the main lever to the pivot frame. (Some Deluxe bugs may be found without the pigtail; ground is achieved through the dot-side return spring.

The early (1939 - late 1940s) upper pivot looks like the standard type -- a protruding adjustable screw with locknut. The screw has a glass jewel embedded in it where it supports the top of the pivot shaft. Later deluxe bugs used a short upper screw, hidden under a red plastic cover (the so-called "jewel") at the top of the frame.

An interesting and fairly scarce collectible (most probably got lost or misplaced) is the foil tag that came with the Deluxe bugs from their introduction in 1939 to the mid-1960s (photo at right). This measures 1-1/8" wide by 1-11/16 high. For larger photos of both sides of the tag, click here and here.

********** COLLECTING VIBROPLEX KEYS **********

A nice collection of Vibroplex keys would contain one of each model. But since the Upright and the Midget are scarce (and expensive), a more reasonable goal might be the six bugs of the late 1930s: Original, Lightning Bug, Champion, Junior, Zephyr, and Blue Racer.

There are also rare models such as the "patent 457" bug, a predecessor to the Model X (Martin said about 100 were made; today one is known), the "Vibroplex Premier," a Vibroplex-built Mecograph (again, only one is known), and perhaps others still waiting to be found.

But a large collection isn't necessary. One nice representative example to use or display can fulfill the "Vibroplex part" of a telegraph or ham radio setup.

********** IF YOUR BUG DOESN'T WORK **********

Close the contacts and no sound out of your test oscillator? No dots and no dashes? Or maybe you have dots, but no dashes? Most problems are easy to track down. A used bug may have been disassembled for one reason or another, and re-assembled incorrectly. Often, the trouble is oxidized contacts; cleaning with a contact file, plain bond paper or a crisp dollar bill should cure that. If it doesn't, you may have a problem I have found only a few times on Vibroplex bugs -- and the cure is the Alabama Fix.

Other issues may arise. I recently acquired a 1960s Champion with the connector strap problem, but correcting that did not cure it. I found a second issue: The dot contact which rides on the pendulum was not making contact with the pendulum, and thus not with ground. Strange, since there are no insulators there. I removed the contact, cleaned the two brass washers, and reassembled it. Now it works well.

************* A BUG DESCRATCHER *************

Mechanical bugs are often prone to generating scratchy dots, due to the lack of contact pressure on make and break. Back in the nineteen-thirties, Ted McElroy offered his Mac-Key bugs with a "dot stabilizer" on the pendulum. This was a simple metal hook which applied some pre-tensioning to the spring-mounted dot contact. Other companies and individuals offered such devices to telegraphers; you may occasionally find one on an old Vibroplex or Speed-X bug. This page shows a few stabilizers, including one currently available from Jim, W0EB.

For those who prefer to descratch their bug electronically, Chuck, WB9KZY (dba Jackson Harbor Press) offers a descratcher kit at very low cost. See it on this page.

*************** THE BUG TAMER ***************

Many Vibroplex bug generate dots too fast for most operators. There are a few ways to tame your bug into QRS mode: You can add weight, or use a Vari-Speed (devised by Joe Hills, W8FYO, years ago, and now available from Vibroplex). But perhaps the best method, and one used even a century ago, is to extend the pendulum beyond the damper, and attach a weight to the extension.
An extension seems to have a better effect on slowing a bug down. It doesn't require as much weight to accomplish a given reduction in speed, and in operaton it doesn't try to twist the pendulum and mainspring as a Vari-Speed mounted weight seems to. Some extensions slip over the end of the pendulum; the one shown here screws onto the threaded pendulum end of a rare Mac-Key.

********** CREDITS and REFERENCES **********

Vibroplex key <"">nameplates are based on my list in the Vibroplex Collector's Guide, third edition. Dates are based on John Elwood's (WW7P) survey. (Thanks to Randy Cole KN6W for providing this information on the web.) Pictures of the plates can be seen here, courtesy of Bob, N0UF.

*************** THE PIGGYBACK KEY ****************

Here is a small straight key that fastens to the wire terminals of a bug. This "Piggy-Back" key was made by Martin Research and Manufacturing Corp. and was offered to "operators who desire an occasional change from the semi-automatic type of transmitting machine." These are scarce - I know of only three. Russ, WA5Y, found one on a Martin Research bug (Flash Key); I found the one shown here on a 1941 Vibroplex Blue Racer, as shown. And Larry, K7KSW, found this one (click here) on a 1919 #4 (Blue Racer) Vibroplex.

If you have one, let me know what key you found it on (if a Vibroplex, the model and serial number); a photo would be appreciated. And a scan of an old advertisement, or a photo of the box one came in, would be especially interesting.

#608GER Norcross Vibroplex double lever.

Horace Martin Vibroplex, United Elec. Mfg Co., Norcross Ga. double lever. This small-nameplate bug dates to 1907-08.

The mainspring is slightly bent to the right and I have not tried to adjust it to operate. The weight does not look original. This would be a scarce addition to your Martin/Vibroplex collection.

#411TGY Norcross Vibroplex Original type.

Horace Martin Vibroplex, United Elec. Mfg Co., Norcross Ga. original style bug. This dates to 1907-08.

This large-nameplate bug has serial number 4165 stamped on the side of the damper upright. This bug is complete and operable, though the contacts need cleaning and adjusting. One weight is not original, and there is an odd screw on the right side of the pivot frame. The paddle and knob are not original. It needs a thorough cleaning.

If you run a bug and ragchew on the air, this is a great conversation starter, as well as a scarce collectible for your station.

#308BAR Mecograph Premier by Vibroplex.

This is the only known Mecograph made by the Vibroplex Company after it acquired the Mecograph company in 1913. See this page for complete information on this bug.


#411TRH Albright license bug.

This appears to be an ATOZ bug. It has had the "first type" Albright license plate affixed (This machine is not guaranteed...) which reads "Special No. 2263."

It is dirty and is missing one of the weight screws, but has traces of the original pinstripe around the edge of the base. The paddle is a replacement. It needs cleaning and adjusting, especially of the dot contact.

Another photo.


#1012TYL ATOZ "Improved Vibroplex".

The most flagrant imitator of Martin's keys was Max Levy, of the ATOZ Electric Novelty Company, going so far as to call this key the "improved Vibroplex." Many of his keys in the hands of operators were spotted by Albright, who removed the ATOZ nameplate and affixed his own Albright license plate. (With a charge of $2.00 to the unlucky operator.) This ATOZ bug retains its original nameplate.

The base and plate on this ATOZ are the nicest I've seen. While it works well (tested on my trusty oscillator), some of the parts, notably the lever, weight and circuit closer, are not original ATOZ parts.

So I offer it as shown, mainly as a display key and a rare addition to your Vibroplex collection.

The nameplate and base may appear red in some photos, but that is the lighting -- they are black.

#M806TGL ... Martin Flash Key.

Here is a Flash Key made by the sons of Horace Martin in the 1930s under the name of Martin Research & Manufacturing Corp. All Martin Research Flash Keys (there were four models) are scarce, because the Bunnell company acquired the rights to the keys shortly after they appeared. (The "Bunnell-Martin" Flash Keys were offered for at least five years, and so are more common.)
This "professional no. 1" model with serial number 5597 is in excellent condition, with a wonderfully clear nameplate. The single large weight may be a later Vibroplex weight; otherwise, this bug is complete and original.

INFORMATION: Horace Martin's first semiautomatic key, the Autoplex, was superceded in 1905 by the Martin Vibroplex. The name Vibroplex would soon be applied to his company itself and all future models of mechanical semiautomatic keys. To distinguish them, the first bug was referred to as the Original model.

The early Original is distinguished by its A0 (serif) or A1 (sans serif) lettered nameplate, damper adjusting screw, and lock screws instead of jam nuts for the lever throw adjustment screws. The serial number is usually found on the damper upright, but earlier ones will have the number stamped into the right front side of the base -- or have no number at all.

Many collectors want one of the first Originals, and look for indications of priority. But there is one more difference that the very first Originals will have: Instead of the U-shaped dot contact spring on the pendulum, look for an unusual flat dot contact spring on a heavier metal arm.

Our Originals for sale are listed below.

#212BTH ... 1905 Vibroplex.

An early first model Vibroplex. Dating from 1905, the type A0 nameplate reads "The Vibroplex, patented Aug. 9, 1904, by Horace G. Martin, New York." This plate is very similar to the A1 plate, but the earlier "zero" plate uses serif letters in the first line. See the photo below.

On early 1905 Vibroplexes a serial number is found not on the damper but stamped on the near right side of the base. The earliest Vibroplexes may have no number at all. I could not find one on this bug, though it may be buried under the thick Japan paint (see last photo).

This is in quite good condition for a 1905. The lever knob and circuit closer knob are the old brown color and appear original; the paddle may have been replaced. The copper "carry handle" (which may be easily removed, but gives historical flavor to this key) required the addition of two holes in the base (or perhaps only one hole, since the hole nearest the pivot frame is exactly where the factory placed mounting holes in later bugs). A thin metal clip was folded over the mainspring, perhaps to speed up the key. It has one weight. The contact on the dash lever is missing but the key works as shown.

About 50% of the gold pinstriping remains, and the black Japan on the base is in very good condition. Needs cleaning. Tested with my oscillator and works.

#792BGY ... 1906 Martin Vibroplex.

The A2 nameplate reads "The Vibroplex, Horace G. Martin's, patents no. 732,648, 767,303, others pending." It has serial number 26xx stamped on the damper upright. This 1906 bug is the second variation of the Original, and is in working condition. It has the usual 3/16" hole in the base near the hot wire connector (common on very early Vibroplexes, perhaps for a screw to fasten the bug to the operating desk).

It probably belonged to a full-time Western Union or railroad telegrapher since it shows heavy use: The fixed dot contact and its jam nut are non-Vibroplex replacements. The wire terminals are of different styles (although both are of the type used on early Vibroplex bugs). The feet look to big to be original. The dash lever contact holder is soldered to its screw. The paddle screw is rusted. The black japan finish is chipped on edges and sides of base, and the nameplate has some light surface rust. (The upper pivot jam nut may be hard to see, it is mounted under the frame bar.)
On the plus side, all the hardware is present including the original weights, paddle and knobs. If you are looking for a very early Vibroplex, here's one to consider.

The B type nameplates: The B type plate was used from about 1910 to 1916. There are now six known variations of the B-shape nameplate. Numbers B1, 2, 3 and 4 were known early on. In general, B1 is found only on the Double Lever keys which have no serial number. B2 is found on Model X keys. B3 is found on Model X and Original keys. B4 is found on the Original, Model X,and Double Lever keys.

After the original listing of B plates (1 - 4), two new variations were discovered. There is the B3X plate (comes after B3) of which two are known, these are on 1913 Original keys with serial numbers 20684 (Randy Cole collection) and 20719. The latest discovery is the B3Y plate on a 1913 Original of which only one has been found (serial number 20751). These can be seen below.

#514MAG ... 1912 Original.

Here is a Martin Vibroplex with the B3 type nameplate; serial number 20074 is stamped inside the damper. This has the scarce flat-topped L damper (with adjusting screw in the swing-arm) found only on some 1912 - 1915 Originals. Note that this 1912 still has the through-base feet mounting screws.

This has been overpainted with black paint. It has a home-made "dot stabilizer" on the pendulum dot contact (a piece of wire used to pre-tension the dot sping). There is one original weight and a non-factory weight on the pendulum. The fixed dot contact appears to be worn down to the screw threads.

A scarce Martin bug and a nice candidate for restoration.

#1114EEO ... rare 1913 Original.

About as rare as you can get, this is one of only two Vibroplex keys known with the B3X nameplate. It has the scarce flat-top damper (with adjusting screw in the swing-arm) found on 1912 - 13 bugs; the 20719 serial number on the damper dates this to 1913.

(The other known Vibroplex with B3X plate is on a similar key with serial number 20684, in the collection of KN6W.)

Condition: About 20% of the gold pinstriping is still visible, although quite faded. The nickel plating is flaking off of the dash lever. The single weight (and certainly its set-screw) do not appear original. The connector strips on the bottom are apparently replacements.

If you collect the rare Vibroplex bugs, don't overlook this one.

Right side.


#814TRL ... unique 1913 Original.

More than rare, this is unique -- the only nameplate of this type known. Recently discovered (August 2014), I call it the B3Y since it is a B style with a serial number of 20751 placing it after the B3X and before the B4 numbers.

This key has the scarce flat-top damper typical of 1912-13 bugs, with the serial number stamped on it.

This appears complete except for a pendulum weight and a replaced paddle. The base finish (which seems to have been nickel) is gone as is the nickel plating of the upper brass parts, which have a dark patina. Some of the locknuts do not turn so need an application of penetrating oil. The bottom of the base is covered with a light coating of rust. It was found as shown; I will provide a usable (though not original) weight for it.

If you are looking for one of each nameplate for your collection, this may be your only chance for a "B3Y plate."

#514BGT ... 1919 Original.

This Vibroplex has a C2 type nameplate with serial number 69334. The black base finish is very good but the gilt pinstriping is all gone; there is the usual opersating-desk mounting hole in the base near the hot wire terminal. The pendulum dot contact appears to be an unusual old replacement. The weight also appears to be an old replacement.

Tested and works very well on my oscillator, but a bit fast with only the one weight.

Another view.


#307TYL ... 1920 Original with bug decal.

This 1920 Original has a C3 type nameplate and serial number 77032. It has the Vibroplex bug decal which was only used on keys for a few years in the late 'teens and early 'twenties. (The hole at the top of the decal is the desk mounting-screw hole found on keys of this vintage.) The decal is unusually complete.

The knob and paddle are reversed -- from the thumb impression on the paddle, this bug was evidently used by a left-handed operator. The black base finish is very good; it has a few small chips on the edges. The key has one weight. It needs cleaning (but be careful cleaning the decal, it may be subject to water damage). The nameplate shows its age and the serial number is difficult to read.

#506TYT ... 1923 nickel based Original.

The nickel plated base finish cost a couple dollars more than the colored or black bases, which was a lot in the 1920s. This explains why they are scarce. The 89xxx serial number on the type D2 nameplate dates this bug to 1923. This old-timer is complete with both weights. It is well used and the finish is worn and freckled. With its early style design it would be a nice addition to a vintage operating desk.

#113TYL ... 1926 Original Standard.

Serial number 97828 on a D3 type nameplate dates this nice Original to 1926. It is complete with its original paddle and knob, and both weights. There are a couple very small black-paint touch-ups where the base finish had chipped. Most of the gilt pinstriping is still there. A great vintage bug from the intersection of the spark/CW era.

Another view.

#314MAY ... 1926 Original Standard.

Serial number 96770 on a D3 type nameplate dates this nice Original to 1926. This is a very nice vintage key, with the early square-shouldered frame and damper. It has both its weights, and operates well.

Most of the faults are minor and would not be noticed until I told you: There are several small chips along the side edges, the front feet are old larger replacements, the paddle is NOS, and the knob is not original. Almost all of the gold pinstriping is gone.

This old bug would be a nice addition to an old-style ham station.

#714TYY ... 1926 nickel plated Original.

Serial number 990828 on a D3 type nameplate dates this nice Original to 1926. It is complete with its original paddle and knob, and both weights. This has one of the nicest plated bases from this era that I have seen; there is very tiny freckling started, but a light cleaning and perhaps a little wax will cure that.

There is a chip in the knob, the knurled nut on the hot wire terminal is a replacement (the original was missing, and a hole has been drilled in the base (perhaps for screwing to an operating desk). None of this would seem to detract from that amazing nickel finish.

#611BHR 1940 VGN RWY Deluxe Original and case.

Rare and historic railroad telegraph apparatus? Some background: I obtained this key, in this case, from a seller in a small town North of Lynchburg, Virginia. It had a tag mentioning "VGN RLW Brookneal." Now Brookneal is a small town South of Lynchburg, and the Virginian Railway (VGN Rwy) passed through it. This railroad existed in name from 1907 (when it was created by the merger of the Tidewater Railway and the Deepwater Railway) until 1956 (when it was merged with the Norfolk and Western). There is a lot of history regarding the VGN, which includes Buffalo Bill, train wrecks, and "the longest yard." My guess is that this key was used by a telegraph operator on VGN.

The key (an early deluxe Original) is serial number 115707 on a D4 (Fulton Street) nameplate dating it to 1940. It is in excellent condition, needing only cleaning.

The carrying case is an unusual and rare top-lid model. This style was never advertised by Vibroplex, and the Eagle Lock Company latch uses a center-pin key (all other Vibroplex cases use a flat key) so it may be from another maker but made specially for the Vibroplex bugs. The case covering shows wear and use.

Rather than break up this interesting set, I am listing the key and case together.

The case.


A note on the WWII era bugs -- The Deluxe models (with red plastic paddle and knobs, "jewel" bearings, and ground pigtail) had a gray painted base ("battleship gray"), since the availability of chrome was restricted during the war. The Standard models had black finger parts and a black wrinkle base finish. The metal nameplates are made of a cheaper material and tend to lose their finish.

#815VOO ... 1944 WWII Deluxe Original.

This is a war-era Deluxe, with the Battleship Gray base. It has serial number 136094 and a D5 nameplate. As a Deluxe it has the jewel bearings and ground pigtail from the lever to the pivot frame, as well as the red paddle and knobs. But this early Deluxe still retains the earlier upper-pivot screw and locknut, and the squared-off damper and pivot frame. It has one large weight.

The base finish is very good. The nameplate is not as bad as many, but it does show age and patina (typical of the wartime plates). There is a chip out of the end of the paddle (see photo) and the key has one weight so it is somewhat fast on dots.

Use this vintage collectible bug as is, or restore the nameplate to bring back its original beauty -- the plate pins can be driven out from the bottom of the base which makes removal of the plate rather easy. A great collectible vintage Deluxe with WWII history for your operating desk at a price much lower than a new Standard model.

#815CAY ... 1944 WWII Deluxe Original.

This is a war-era Deluxe, with the Battleship Gray base. It has serial number 136722 and a D5 nameplate. As a Deluxe it has the jewel bearings and ground pigtail from the lever to the pivot frame, as well as the red paddle and knobs. But this early Deluxe still retains the earlier upper-pivot screw and locknut, and the squared-off damper and pivot frame. It has one large weight.

This bug is in excellent condition; the base finish is near new. The nameplate has apparently been polished by the previous owner. Overall this is one of the finest Vibroplex bugs I have been able to offer -- why pay over $200 for a new one when this one has more history, collectability and beauty for a lower price?

#1113BAY ... 1945 Original Deluxe.

A beautiful Original Deluxe, serial number 142xxx and D5 plate dating it to 1945. With the WWII restrictions on the use of chrome, the Deluxe was given a "Battleship Gray" finish. This finish is a nice sparkling or crackle type finish, unlike the flat-gray finishes used later. And as a Deluxe, it does have the ground pigtail from the mail lever to the pivot frame, and the red plastic paddle and knobs.

This is one of the nicest WWII Deluxe bugs I have had -- the base finish is excellent, and this key does not have the poor tin-steel nameplate found on many WWII Viboplexes. In many ways, this Deluxe is nicer, and more interesting, than the chrome-base models. It has one weight, and is a very fast bug; you may want to add a weight, a Vari-Speed, or a pendulum extension.

#213BEL ... 1951 Original Standard.

Serial number 173517 on a D6 nameplate dates this bug to 1951. This is in good operating condition. It is complete with both weights, but still somewhat fast on the dots. There are chips in the black crackle finish on the edges as shown in the photos. A nice working bug for your operating desk, though the contacts could use a little more cleaning.

#305TOR ... Unusual 1955 Left-handed Deluxe Original.

Serial no. 189xxx, D6 type nameplate (833 Broadway NY). Left-handed Vibroplex bugs are scarce, but what makes this one even more unusual is that the wire terminals are on the right side! It is the only one I have ever seen made like this. And no, this is not an altered right-handed bug.
This chrome plated Original is complete with two small weights. Very good condition except for some freckling of the base in front of the pivot frame, see the photo. The screw which normally fills the hole in the left frame arm is missing, or was never installed. Another view

#214WGE ... 1958 Standard Original.

Gray base, serial no. 204250, D6 type nameplate (833 Broadway NY). The plating on the large single weight does not match the nice chrome of the other parts. With a little cleaning of the base finish you would have a nice vintage Vibroplex for your station.

#113TTG ... 1963 Original.

A Standard model Original with the gray painted base. The serial no. 231740 and D6 type nameplate (833 Broadway NY) dates it to 1963. It is original and complete with one large-size weight.

The nameplate shows wear, and a previous owner has marked the terminals + and -. There is wear on the painted base finish (see last photo). A good used bug; why pay more? It works well as tested on my oscillator.

This is in good used condition. It works well as tested on my oscillator.

The Maine Vibroplex bugs.... Peter Garsoe bought the company in 1978 and moved it to Maine. His early bugs used up the New York inventory, including D7 type nameplates. The nameplates were glued to the base (no rivets). When the circuit closers ran out, he put a screw in the base hole; later Maine bases were pure "radio" bugs, with no circuit closer and no hole in the base needing to be filled. The Maine nameplates are identified by having no address. These late Maine Vibroplex keys are very nice, plain, uncluttered bugs.

#413CPH ... 1986 Maine Standard Original.

This is a Maine bug, serial no. 523xx, D8 type nameplate, dating it according to Elwood's list to 1986.

This is the standard model, with a gray base made with no circuit closer. It is in excellent, perhaps unused, condition. It has one small weight on the pendulum. A scarce and collectible bug for your operating desk.



#811CRA ... 1991 Maine Standard Original.

This Maine bug has serial no. 66xxx, D8 type nameplate, dating it to 1991.

This is the standard model, with a gray base (photo may look tan but it is standard gray) and no circuit closer (note it does not have the hole for the closer screw). It is in excellent condition with probably no use. It has one large (3/4" long) weight on the pendulum. A scarce and collectible bug for your operating desk.



#1113BGE ... 1992 Maine Standard Original.

This Maine bug has serial no. 68876, D8 type nameplate, dating it to 1992.

This is the standard model, with a gray base and no circuit closer. It is in excellent condition with no use, and comes in the original box. It has one large (3/4" long) weight.

This includes the original paperwork: parts list and diagram, unpacking instructions, warranty information, and a two page reprint from QST by VE2AGO on adjustment. A scarce and collectible bug for your operating desk.

#1214BRY ... 1994-95 Maine deluxe Original.

Serial no. 80333, D8 type nameplate. This dates to the period 1994 - 95. This Maine bug has one large weight, but it is still somewhat fast on dots. It is in like-new condition but the chrome needs polishing. This is a nice find for your collection or operasting desk.

#X01CPY ... Mobile AL Standard Original.

Serial no. 105390, D9 type nameplate (11 Midtown Park E., Mobile AL USA). This dates to the period 1995 - 2010. Peter Garsoe sold the company in 1994 to Mitch Mitchell, W4OA, whereupon Vibroplex moved from Maine to Alabama, where it remained for 15 years. This Mobile Original has one large weight; the key is in like-new condition. These Vibroplexes carry the last of the embossed-metal D-type nameplates.

Appearing in 1948, the Presentation was the Company's "Super Deluxe" model with a gold-plated brass plate on the base, jewel bearings, "super speed control" adjustable mainspring, and ground pigtail on the lever.

For a small charge, you could have the company engrave your name or call letters on the gold plate (some did, some didn't). And based on those found, the circuit closer was an option; when not selected, a screw was placed in the lever hole, and the lever ground tab under the dash contact post was not installed.

The "real" Presentation was discontinued in 1979 when the adjustable mainspring was dropped. The "Presentation" then became just a pretty variation of the Original. Today it is offered by the company as the "Original Presentation" at $340.00 (the "Original Gold" with the base itself gold plated is $380.00). But if you want the best looking and nicest bug the Company ever produced, look for an early (1948 - 1978) Presentation. You will get a vintage collectible key.

#401BCA ... left handed 1957 Presentation.
Here is a scarce and collectible left handed presentation. The serial no. 199xxx, 833 Broadway NY, D6 plate dates this one to 1957. A very nice Presentation in very good condition. It has one small weight on the pendulum. This has the circuit closer option, and no call letters on the plate. Note that, as a left-handed model, the Company filled the lever tension screw hole in the left-side frame arm with a screw (frames were drilled for right-hand use, and modified when a left-hand bug order came in).
The plate shows a bit of age -- examine the photos, keeping in mind that photographs of keys (or cars, or houses) usually look somewhat better than the actual object. It has one small weight, and is quite fast so you may want to add another (available from the Company). As usual, the gold-plated plate needs a little cleaning, but be very careful and gentle in doing so as the 24K plating will scratch easily. Do not use rough cleaning compounds.

#414TTG... 1972 Presentation.
A beautiful unused, new-old stock Presentation with its box. The 269540 serial number and the D7 New York nameplate indicates a manufacture date of 1972. This bug was ordered without the shorting switch; a screw fills the lever hole.

The original owner of this key never used it; it still has the rubber shipping bumpers on the main lever. There is a tiny ding in the gold-plated plate (look between the dot stop screw and the fixed dot contact post) and you may find other micro-imperfections on the plate (possibly factory-inflicted), but I doubt you will find a nicer Presentation for your operating desk.

INFORMATION: The first double levers were made in Norcross GA in 1907 and have a "half-frame" pivot support. These were quickly followed by the full square pivot frame; these carried the Norcross GA nameplate. (This plate came in two sizes, I believe the Norcross DL only had the smaller 2-1/4" wide plate). plate.)
Martin then moved to Atlanta. The 1908 - 1909 double lever also had the square frame and carried the Atlanta plate. This square frame was continued in the early NY double levers, starting with the B1 plate in 1910.
The last double levers, around 1926, had a round-shouldered pivot frame and the D3 nameplate.
DL serial numbers: The Georgia DLs may or may not have a SN, some do, some don't. If they do it is somewhere on the damper upright. The early NY DLs (B1, B2 plates) do not have SNs (as far as I know). By 1913 (B4 plate), they do have SNs (D5000 series numbers). the last plate to be used on the double lever was the D3 plate (1926).

#514EEY 1910 Double Lever.

This is one of the earliest double levers made in New York after Martin's return from Georgia. It carries the B1 nameplate and the early NY circuit closer. But note especially that Martin used (briefly) the Norcross / Atlanta style damper swing-arm; this is a rare feature for a B1 double lever. Typically (for a B1 plate Vibroplex), it has no serial number.

This appears complete (with one weight). The fixed dash contact seems to be an old replacement; the dot contacts certainly are. This needs complete restoration: The nickel plating is gone from the upper brass parts, and the base finish it totally gone; there is a light patina of rust on the base. Although the pendulum is free and it does generate dots, many of the other parts need an application of penetrating oil (I recommend Kroil) to loosen them.

This is a rare early model for someone who enjoys restoring their keys -- or free it up and use it on the air as is!

#401BCC Double Lever.

This is an early New York Double Lever. The square pivot frame, type B4 nameplate, end-pivot circuit closer, and D5189 serial number all work to date it to 1913. It has the remnants of an Albright decal on the base (typically only found on bugs in the 1913 - 1915 era).

Both dot contacts are later replacements, there is no weight, and one paddle is broken. The damper is slightly cocked, probably from a drop some decades ago. Overall this almost-century-old key needs only minor attention to be a star of any Vibroplex collection.

#1105EOT Double Lever.

A later Double Lever with the cloverleaf style pivot frame; the C3 plate and 76579 serial number date it to 1920.

This key was obviously used by a professional telegrapher: The wedge cord is expertly attached to the terminals, and one wedge leaf is stamped WU TEL CO (stamped on the back of the leaf and reads backwards). And despite the heavy looking homebrew weight, it is adjusted to be fast.

The base retains remnants of a Vibroplex decal, and pinstriping. The nameplate is hard to read, the dot lever stop screw is a replacement, and the head of the upper pivot screw is gone. Interestingly (and unusual for such old bugs) it operate nicely as shown, just as found.

A great collectible, complete with evidence of its past use and history.

SHIPPING a Model X: On old keys it is sometimes difficult to remove the knob and paddle for shipping, so the entire lever assembly is often removed. To do this on an Model X, remove the two upper pivot bar retaining screws, and back the dot lever spring tension screw out to release the spring. (See this photo.) Then lift the lever assembly up and out.
The photos show an early Model X; the procedure is the same on the later improved model.

#205ETHG left handed Vibroplex Model X.

A left-handed Model X Vibroplex bug. Unusually fine condition. One other LH model X is said to exist, but I also heard that its condition was not as nice as this one. Serial number 599xx on a C1 type nameplate dates it to 1917.

#1004EEY ... Early Model X.
Horace Martin's "single lever direct point transmitter," soon known as the Model X, was introduced in 1911. The one offered here is a scarce early model; it has a B4 type nameplate ("Horace G. Martin" on the plate) and serial number 12356 on the terminal connector strip, dating it to 1913-14 (Elwood's list says "no numbers reported" in this range, but that's where it would fit).

Note that first-style Model X bugs have the mechanism mounted to a sub-base, and on the "early early" models (such as this) the screws for the feet protrude through the base, as on this one. Original and complete; needs cleaning. The base casting and the black finish appear crude; there is no pinstriping.

#1001TRG ... Improved Model X.

The improved model offered here has a C3 type nameplate with serial number 75xxx, dating it to 1920. It also has the bug decal (quite faded). It is original and complete, although the black finish is chipped on the corners. Some of the original gold pinstiping remains.

It is complete and all of the parts are correct and original. Tested on my oscillator, and works -- excellent dot action, althought the dash lever throw is a bit long so you may want to adjust it to your fist.

#V907TLR ... 1919 Blue Racer on large base.
A rare Blue Racer on the "old style [large] base." From 1919, with C2 type nameplate and 67xxx serial number. It also has the cloverleaf frame found on Racers of this era.
Good condition, complete with both weights. The paddle and the dash spring are replacements. An early owner's initials "HLL" are scratched into the base -- that it is initials and not call letters suggests that this was used by a railroad telegrapher.

#815VOY ... 1945 WWII Deluxe Blue Racer.

This is a WWII Deluxe Blue Racer; it has serial number 140833 on a D5 nameplate and dates to 1945. It has the red finger pieces and ground pigtail, but the wartime gray base. There is one weight, and the thumb-paddle has lost a chip at the screw. The main lever stop and rest screws and locknuts are not the usual -- but they match and I believe they are original (I attribute their use by the factory to wartime exigency, you may disagree).

The base finish is in excellent condition with no chips, though the wartime zinc (?) nameplate has suffered the loss of finish. If you restore the plate, you will have a fine Blue Racer at a low cost.

The new style Blue Racer appeared in 1946 with a pivot frame and damper styled like those on the Original, only smaller. Personally I consider these, whether Deluxe or Standard, the prettiest Blue Racers made. The earliest ones have a D5 nameplate (833 Broadway, 6 patent numbers with "other patents pending"). The last Blue Racers were made in 1967.

#314TYL ... 1946 Deluxe Blue Racer.

This early new style Blue Racer has serial number 152490 on a D6 nameplate (833 Broadway, "patented," no patent numbers), and dates to 1946. It is the Deluxe version with red fingerpieces and a chrome base. It has the "jewel" bearings, and a ground pigtail from the main lever to the pivot frame.

This is complete and original, including both weights. The base and other chromed parts are in excellent condition, but they do need cleaning.

#VBR191 ... 1955 Blue Racer.

A standard model, new style Blue Racer, this has a D5 nameplate with the serial number 191xxx dating it to 1955. Complete with two weights.

There is a small chip in the paint on the upper left edge, and the nameplate could use cleaning. Overall this is in very good condition, all ready for your mid-fifties vintage operating desk.

Note. The D7 style nameplate, 933 Broadway with no patent data, appeared in 1963.

#BOX406 ... Blue Racer carrying case.
This case dates from the 1930s - 40s, and was made for the 2-1/2" wide Blue Racer; the photos show it in front of an Original case for comparison. Unlike the larger cases, which were made for the Original, Champion, and Lightning Bug, these cases were made to fit only the smallest Vibroplex and so are seldom found. The outside measurements are about 3-3/4" wide x 8-1/2" deep x 3-3/4" high.

This is in very good condition. The handle is missing, and there is light scuffing on the lid corners. One small area on the front edge of the inner lining is torn. No key.

The Vibroplex "No. 6" was introduced in 1927, and was a major departure from the Original and the No. 4 Blue Racer. Its frame was assembled from posts and triangular plates, the pendulum was a flat bar, and the damper was a bridge shape (M type) with a heavy hanging wheel. It was first offered with the usual black Japan and nickel plated base, as well as the now-scarce red, green or blue colored base. Its last appearance was in 1979.

The Lightning Bug is a favorite among many collectors and CW operators, who feel it surpasses the Original in beauty of design and smoothness of operation. The Army Signal Corps liked it as well: It became the J-36 bug for World War II.

#414NPY ... 1928 Lightning Bug.

This Lightning Bug has a D3 plate and 103102 serial number dating it to 1928. It is in very good condition with all original parts. It has most of the gilt corner decorations; the black japan base finish is excellent with only a couple small chips on the far back side. The upper "bright parts" are not so bright, they carry the patina and oxidation of 80 years.

A nice vintage Vibroplex for the CW operator, or a good example of the Lightning Bug for the collector.

#307BHR ... 1932 Lightning Bug.

The 1064xx serial number on a D3 nameplate (Fulton Street, seven patents) dates it to 1932. The nickel plated base (an extra-cost option) has some rubbed areas on the edges and a few freckles on the top, but it should polish up nicely. Two items are replacements: the dot spring tension screw and locknut (appears chrome plated), and the circuit closer knob. Otherwise it's a nice No. 6 for your operating desk.

#114MRG ... unusual 1936 Lightning Bug.

This Lightning Bug has a D3 plate and 109174 serial number dating it to 1936. This has a very flat or minimal kind of wrinkle finish in a satin hue. Perhaps Vibroplex was experimenting with base finishes to replace the black Japan (real black wrinkle appeared in 1939.) The gilt pinstriping is mosly present, and it, too, seems done with a dull or satin type paint. It is a very nice effect, and the only one of its kind I have seen. Cosmetically, the black finish is excellent with no chips or defects.

This key is complete and works well as tested on my oscillator. The paddles and circuit closer knob are non-original as seen in the photos.

#714NRY ... 1944 Deluxe Lightning Bug.

This is a Deluxe model Lightning Bug from the WWII era; it has the dark "battleship gray" base. The D5 nameplate and 27565 serial number date it to 1944. The red knobs and paddle have acquired a nice patina with age, something you don't see with the plastic used on the modern Deluxe Vibroplexes. The base finish is in very good condition with no chips; however, if you look at it "just so" near the wire terminals you will see a light stain. This is hardly noticeablein normal use on the desk. Overall it is one of the nicer WWII Deluxe bugs I have had to offer.

#314BPE ... 1944 Lightning Bug with Case.

This Deluxe model Lightning Bug has a D5 plate and 136812 serial number dating it to 1944. It has the ground pigtail (as do all the Deluxe models), and the early-style glass-bead upper pivot. This has a beautiful, dark Battleship Gray base (darker than in the photo) in excellent condition. The nameplate, like most WWII plates, appears to have some tarnishing.

This key comes with its original case. The leather handle is broken, and the metal parts have been painted black. The external fabric covering is in good condition, with only a couple of small dings at the back.

This belonged to Stephen Schmalzel, W8WGU, an active CW ham radio operator and sergeant in the Army, who likely bought it new. He was in charge of commmunications wherever he was assigned. That's a photo of his 1940s girlfriend inside the case cover. This key was acquired from his nephew. It is a nice key with known provenance; I have more information on the first owner of this key which will be passed on to the buyer.

This is in good original condition, and works well. It should polish up nicely for your operating desk.

This is a Standard model Lightning Bug with a D6 plate and 159xxx serial number dating it to 1948. Sometimes we aquire a key that is too nice not to get the dust off of, so I cleaned and oiled the base (with Outer's gun oil) and polished the nameplate. It really sparkles now. There is not one chip or scratch in the black crinkle base finish.

You may want to polish the chrome parts, and the worn paddle shows it has seen a lot of use... otherwise it is a beautiful vintage Lightning Bug for your vintage operating desk.

According to my book (Vibroplex Collector's Guide, 3rd edition, 2001, out of print) the Martin Junior was produced from 1921 to 1939, and the D1 nameplate came out in 1921. I hereby revise both comments. I (like most collectors) date Vibroplex bugs according to John Elwood's list, and since writing the book I have found Juniors with the D1 plate bearing serial numbers dating to 1920. In fact, a recent find is a Junior with a C3 plate and 1920 serial number (75564)!

#1214TOO ... 1920 Martin Junior.

This is the earliest Martin Junior known, based on the serial number. It has a C3 nameplate and number 75564, dating it to 1920. Being one of the first Juniors made may explain the left-side orientation of the nameplate (the following D type plates on the Junior faced right, as on the other models).

This is in very good condition: It has most of the gold pinstriping. There are a cople of chips inthe black japan finish at the back right corner. The weight and its screw appear to be replacements. The contacts are an unusual large size, though their screws appear original. Overall this is a nice collectible and a rare find for your vintage operating desk.

#1003TOY ... 1920 Martin Junior.

The serial number on the D1 plate on this Junior - 803xx - dates it to 1920, according to Elwood's list, quite a low number. It shows age and use: One weight, poor knob, the gold pinstriping is very faint, there is a large chip in the finish at the front right corner, and the finish has craze cracks (seen in second photo). Includes a cord and wedge, which was used to attach the operator's personal bug to the company hand key on the operating desk. Second photo


#305TTY ... 1920 Martin Junior.

Another very early Junior, with serial number 806xx on a D1 plate, dating it to 1920. Very little of the gold pinstriping is left, it has one weight, and the dot contact on the pendulum is a later replacement. Otherwise all parts (including the knob and paddle) are original. Second photo


#492TYY ... 1921 Martin Junior.

This is the nicest Junior I have had, it has been in my personal collection for twenty years. The D1 nameplate and 880xx serial number date it to 1922. The pinstriping is practically all present, and bright. The black base has only one tiny chip on the far left edge. It is complete and original with both weights. A light cleaning of the base will make this look practically new.

#113CPR ... 1936 Martin Junior.
A very nice Junior -- This has a D3 nameplate and a 109xxx serial number, dating it to 1936. The black base has an unusual and very attractive matte finish (compare the shiny Japan finish on the 1921 #492TYY above).

The pinstriping appears 100% intact; this key is complete with all original parts and both weights. The paddle has a slight curve, possibly from years of (careful) use, and there is a 3/4" scrape in the finish on the left side but due to the matte finish is hardly noticeable.

Take a little time to clean and buff the upper plated parts and you will have a scarce vintage Vibroplex for show or operating.

Although the Zephyr was offered for almost twenty years -- from 1939 to 1958 -- it is one of the scarcer models. One noted collector acquired every Vibroplex model, and the Zephyr was the last one he found -- after the Upright and the Midget !! The Zephyr is similar to the Champion, with its flat pendulum and I-style damper, but it is on a narrower (3" wide) base and has a circuit closer.

#815VGA ... 1954 Zephyr.
Zephyr with D6 nameplate and 183893 serial number dating it to 1954. This is in excellent condition. The black wrinkle base finish is great, there is only a small flat spot in the finish about halfway down the left edge (see photo).

I rarely clean the keys I offer here, preferring to leave that to the buyer, but I did clean and oil this base because it just seemed a shame not to show it at its best. The nameplate shows some age with a couple small dents at the lower edge.

If you have been looking for a Zephyr, you cannot do much better than this one.

#113TAL ... 1956 Zephyr.
Zephyr with D6 nameplate and 196xxx serial number dating it to 1956. This is in near-new condition with no defects. I have an identical model that I bought in 1956 (and still have !!) and the only difference I see is the washer under the weight screw -- mine is round while the one on this bug is rectangular. See the photos.

One of the nicest Zephyrs I have seen.

The Champion is a nice "radio bug" (no circuit closer) for the CW operator. It is an excellent choice for the modern operator who wants a vintage bug on his operating desk, or for the collector's display shelf. This model has not been made by the company for over thirty years, and good examples are becoming scarce.

The Champion was the Company's basic, low-price bug; it was never offered in a deluxe version. The base was black crackle from its introduction in 1939 to the early 1950s, followed by gray crackle, then beige.

The Vibroplex Champion was also the bug of choice for the U.S. military after WWII. No longer did the Signal Corps J-36 have a special nameplate, and no longer did the Navy bugs have a base with cast-in "property of U.S. Navy." But they are identifiable as military bugs from the ink stamp on the bottom of the base. We will list them here, and you can also see them Champions on our U.S. military keys page -- look for them under J-36 keys, and under U.S. Navy keys.

#V410BOG ... 1944 Champion.
The D5 nameplate and 137332 serial number date this Champion to 1944. This is complete with all its original parts. The black crackle base finish is perfect; the nameplate is darkened with age (and may be suffering from the use of wartime materials). This is a great example of a WWII Champion.

#514MOG ... 1957 Champion.

The D6 nameplate and 197181 serial number dates this Champion to 1957. This is complete with all original parts; clean the contacts and it will make a nice vintage radio bug for your operating desk.

The base finish is in very good condition, though it needs cleaning; the nameplate is quite tarnished. That is tape residue on the upper pivot plate -- I cleaned most of it off after the photographs were taken.

#413CAH ... 1960 Champion.
A nice gray-based Champion. The D6 nameplate and 214xxx serial number date it to 1960. It is all original and in very good condition -- the front left corner of the base is rubbed, otherwise I found no flaws. It appears to have had very little use and no wonder: the connector straps under the base were incorrectly installed and I had to apply the Alabama Fix.

#1213CGR ... 1964 military Champion.

This is the bug ordered and used by the military in the mid-1960s. It is a 1964 Champion, serial number 239228 with a D7 nameplate. The military part number stamped on the bottom is 1N 5805-312-2750; the contract number is N126-10052A (see the Vibroplex Collector's Guide, page 73). Vibroplex provided bugs to the Navy and to the Signal Corps after WWII; I believe this is a Signal Corps key, so would be classified as a J-36. While the military versions such as this are scarce, the only difference between the stock Champion model and the military verision is the stamp on the bottom.

This key is in excellent condition, perhaps never used: It still has the lever and upper pivot screw protective rubbers as shipped from the factory.

#1213DRG ... Unusual 1976 Champion.

This gray-based Champion has a D7 nameplate and 378870 serial number, dating it to 1976. Note the location of the nameplate; it is the only one placed like that on a Champion that I can recall. Also note that the hot wire terminal is the one closest to the damper; again, an unusual position.

It is all original and in good condition -- but it needs cleaning, especially of the chrome parts (note where I have cleaned a spot on the upper pivot plate). It works well, though it would operate more consistently if you clean the dash contacts. If you collect factory oddities, you should consider this one.


#697-284 ... 1979 Left-handed Champion.
This is an early Maine Vibroplex. It has the short-lived beige base, and the late D7 nameplate (388xxx serial number) glued to the base. Peter Garsoe, the new owner of the Company, used up the last of the New York plates before making new (D8 style) plates. And this is a rare left-handed Champion! It is in excellent condition, and has never been used since leaving the factory.

The electronic keyer paddles below are arranged in order of manufacture date, so the various models (Vibrokeyer, Iambic, etc.) may be mixed as you go down the list.

The Standard (painted base) Vibrokeyers and Iambics are now offered with an upgrade to the jeweled pivots which are used on the Deluxe model. The Standard models that we list have the standard bearings unless otherwise stated.

#114CLG ... 1966 Vibrokeyer.

Despite the beige painted base, this appears to be an early Deluxe: It has the jeweled bearings and the ground pigtal to the main lever. The serial number is 245476 on a type D7 nameplate.

There are a few small chips in the base finish, the red button ("jewel") is missing from the top of the pivot frame, and the knob and paddle are no the originals. This is a good single-lever paddle for those who do not like the iambic type

#514BGL ... 1982 Maine Iambic.

This Iambic (two-lever) paddle has a 42905 serial number on a D8 nameplate, indicating it was made in Maine in the early 1980s. It has the standard model pivots (not jeweled), and has a light gray painted base.

This paddle is in excellent condition needing only a light cleaning of the chrome parts to make it look brand new.



#1214BGA ... 1994 Maine Deluxe Vibrokeyer.

A D8 nameplate and serial number 80317 dates this Deluxe Vibrokeyer (single lever paddle) to 1994 - 95. It shows no signs of wear and may be unused, but the chrome needs polishing.

ACCESSORIES AND PARTS ... cases, cord and wedge, anything else.

#VARISPEED1009 ... Vari-Speed adapter.

Here is an infinitely variable speed adapter for the Vibroplex round-pendulum bugs (Original, Blue Racer, etc). I believe this one was offered by Vibroplex some time ago, though they do not offer them today. Slip this on the pendulum, clamp it in place by the small allen-head screw, and place the weight on its arm. By adjusting the arm back or forth you can vary the speed of your bug a lot more than with the weight on the pendulum.

Offered is the vari-speed only, not the weight or bug shown. Excellent condition.

A bug case is practical and useful for protecting or transporting your Vibroplex -- to club meets, a fellow ham's shack, or to field day, for example. They are also collectible: The company no longer offers bug cases, so if you want an original Vibroplex case, look for a used one. If possible, match its age to your key. We occasionally come across them, and will offer here what we find.

Bug cases can be as scarce and collectible as the bugs themselves. They have varied in size, construction, lock and key, and handle style from 1905 to the present. (At right, a 1905 Vibroplex case.) Handles have been a metal loop, leather, and plastic.

Lock types have been basic clasps (1905, see right), fancy center-pin or barrel key locks (1915, see below), simple pre-WWII center-pin (barrel key) locks (click here), and post-WWII flat key locks. The flat keys can be found in a couple different styles.

This appears to be the second variation of the case: It has a metal loop handle (although slightly different in design than the one above - possibly a cost-saving change), but the major change is the center-pin lock (for a barrel key). The lock on this case is stamped Eagle Lock Co.

These early cases have large, exposed hinges, as compared to the smaller, semi-hidden hinges on later cases. Also, the inside of these cases is not finished with felt like later ones.

A note on the hinges: First, there were two large hinges attached to the back of the case with the wings exposed, and three screws in each wing. The second had similar hinges but the wings were attached with two rivets. Third was one 2-1/2" long hinge, attached to the edges of the case and top with three screws on each wing. Finally, two 1" wide hinges were used (although one 1944 case was found with 1-1/4" hinges), with the wings attached to the exterior of the case and top but covered by the finish material.

This large bug carrying was obtained by Fabio, IK0IXI, in 2012. It contained a nickel-plated Original dating to 1915 (B4 plate). It has an Eagle center-pin lock, which takes a barrel key. Nothing too unusual so far... But note the Eagle Lock Company latch: You have to push the bottom button to the right so that the latch can be opened. Little tabs on either side block the latch until the lower button is pushed.

Another view of this lock.

A case with the same latch appeared on ebay holding a 1914 (early) Model X bug -- this case appeared to have to hinges, butted close together. But it is the latch that is of interest.

I saw another case with the same latch on ebay; it contained a 1918 Original (with C2 plate, SN 60633). This case has the third style hinge: 2-1/2" long, attached to the case and top edges.

In fact, this case was offered in a couple of early ('teens, 1920s) Vibroplex catalogs (the only two that have Horace Martin's picture in them), although it seems this case was not available as late as the catalogs indicate. It makes for an interesting, and scarce, carrying case. I will call it the "bottom release button" latch and place it in the 1914 - 1918 timeframe (since another lock without the release button made its appearance in 1918).

I found this on the internet... It came with a 1940 Original Standard model Vibroplex. Another unusual case lock. Click on the photo for a larger view.

The 1915 and 1940 case latches above are odd, because they are attached by screws. All other original case locks (sometimes called a "locking catch" by the manufacturer) are normally riveted to the case. The 1940 latch is the only one I have seen, so might represent an owner's attempt to protect his key with a better lock of the era.

What looks like a half-mortise lock was seen on a 1924 case; the case also had the single 2-1/2" hinge. Another view. This may have been a brief experiment by Vibroplex, abandoned due to the cost of the lock or expense of installation. I have included it in the list below.

This is an interesting top-lid case found with a 1940 Vibroplex. It has a leather handle and barrel-key lock. I do not know if it was sold by Vibroplex.

In addition to the handle and lock, the cases differ in the interior treatment. The chronology below includes what I have seen in this regard.

VIBROPLEX CASE CHRONOLOGY Based on cases I have seen, this is the design sequence of the end-opening cases, used for over half a century. Years are based on the serial number of the key found in the case; I have included only those cases which appear to be original to the key found within.
This list is a work in progress. The sequential numbers are not "case type" numbers since they are subject to change as I update the list and perhaps interlineate other variations found. The years are based on keys found in cases. Since an early bug may be found in a later case, or vice-versa, there may be some overlap or inconsistencies; these will be eliminated when a sufficient number of examples have been examined.

Early cases have hinges with fancy, exposed wings, and a metal loop handle.
1. Metal loop handle, latch closure, two large hinges with exposed wings attached by three screws in each wing (1905, 1907, 1913, 1920; unfinished wood interior). The earliest cases have the latch on the cover (opening end) and the loop on the case; on the 1913 and 1920 cases I have seen the latch is on the case and the loop is on the cover.
2. Metal loop handle, barrel key lock, two large hinges with exposed wings riveted to case (unfinished wood interior)
Later cases have rectangular hinges with the wing(s) on the case edges or concealed under the case cover, and a leather handle.
3. Leather handle, usually one 2-1/2" hinge, barrel lock key and latch has bottom release button (1914, 1918)
4. Leather handle, one 2-1/2" hinge (3 screws in each wing), barrel key lock (1918, 1918, 1920, 1923, 1926, 1927, 1936 black felt interior, 1944 felt missing)
5. Leather handle, two 1" (1-1/4" found on one) hinges, barrel key lock (1944, 1944, 1944, 1945 tan felt interior // 1944 green felt interior).
6. Leather handle, two 1" hinges, flat key lock (1946, 1946, 1947, 1948 tan interior)
7. Leather handle, two 1" hinges, flat key lock (1948, 1951, 1951, 1955, 1961, 1963, 1967 green felt interior)
8. Plastic handle, flat key lock (Began 1963? -- The last of the end-opening cases.)
Then followed the modern top-opening case with plastic handle and foam-padded interior......

Some of the various case styles can be seen below.

Bug Dimensions and Case Sizes
The large base modern Vibroplex bugs (those with thick conical feet found on bugs with D7 plate, 1966 up) may not fit in vintage cases; the hold-down bars inside the older cases are not high enough to accomodate those keys.
Also, the older cases may not accomodate some very wide bugs. I have found that some WWII era Originals are slightly wider than 3-1/2 inches; a 3-9/16 wide bug is too wide for some cases.
Finally, some older large cases may not accomodate newer bugs due to length: A newer Original with the oval paddle may be 1/8 inch longer than an old Lightning Bug, just a bit too long for some older cases. For example, a 1948 - 63 case will accept all large bugs which are no more than 6-3/8" in length, but will not accept late bugs such as those with square-cut 6-1/2" long bases (these bugs also usually have the new type conical feet, for example a Maine bug).

The Small Cases

The Blue Racer case. Most of the above information is gathered from inspection of the large cases (for the Original model, etc). The smaller cases can also be dated with that information. The smallest case is that for the 2-1/2" wide Blue Racer; the case measures about 3-3/4 x 3-3/4 x 8-1/2 inches on the outside -- compare this to the Original (large bug) case which measures about 4-1/4 x 4-1/4 x 9 inches. Compared to the number of large bugs sold in their various models, the Blue Racer is scarce, and this applies to its case as well.
Comparison: Large case at top, Blue Racer case at bottom.
Blue Racer case. Note spacer and side-stop inside.
With Blue Racer inside.

The Martin Junior case. This bug was 3 inches wide; it falls between the large bugs and the Blue Racer, as would its case -- but I have never had one so cannot provide dimensions at this time.

If you have a concern, let me know what case you are interested in, and what year and model bug you propose to put in it, and I will try to check the fit.

USA Shipping of any case is $12.00
These will be listed below in chronologically, earliest to most modern. Year of case is usually inferred from a bug found in it, or by design characteristics (see above).

Smaller cases (for Blue Racer or Junior) will be listed with their model, in the keys for sale lists above.

#1114EEO3A ... Early carrying case.

Rare first style case. From the key found in it, and the hardware, I date this large bug case to 1913. It is essentially the same as the 1905 - 1920 cases, but the reversed latch indicates it was made late in that period.

This has wear on the cover corners and the back end has been completely replaced with a piece of wood, painted black; it is neatly done. These first style cases are very hard to find in any condition.

#114CCB ... Second variation carrying case.

I date this style of bug case (metal loop handle, center-pin lock) to appearing next after the 1905 case -- perhaps around 1907 - 1910. This is similar to the first case but it adds the security of an Eagle Lock Company barrel-key lock, and to prevent tampering the hinges are attached by rivets instead of screws.

There is wear on the front corners and edge; the back shows the greatest damage, and would benefit from repair in that area. Inside, it is missing the wooden restraining strips. See the photos. As with the 1905 case, this second variation is rare.

#VCASE208TTA ... Large bug carrying case.
1944 - 1945 era case... Made for the 3-1/2" wide based bugs (Original, Lightning Bug, etc), this case has a tan interior. This case is in very good used condition and includes the key. Note that this has a center-pin lock (uses a barrel key) rather than the later flat-key lock.

There is some wrinkling at the bottom of the interior felt, and the patina on the lock shows its age. The handle is intact and there is no dama ge to the exterior; it needs only cleaning.

Key and lock


#815CEG ... Large bug carrying case.
1944 - 1945 era case... Made for the 3-1/2" wide based bugs (Original, Lightning Bug, etc), this case has a tan interior, barrel key lock, and two hinges (unusual, the hinges are each 1-1/4" wide rather than the more common 1" wide). This case is in very good used condition -- the black case wrap is unusually fine, there is some scratching on the lock, and the leather handle is missing. If you can replace the handle you will have a fine carrying case.

Another view


#715BLY ... 1948 - 1963 large carrying case.

Dated by the handle, flat key lock, two small hinges, and green felt interior, this is the last of the leather handle cases. This will accept all large bugs which are no more than 6-3/8" in length. It will not accept late bugs such as those with square-cut 6-1/2" long bases (these bugs also usually have the new type conical feet, for example a Maine bug).

This is in very good to excellent condition; the handle is intact and the case wrap is near fine. It is missing one tack foot, and there is patina on the lock. The felt interior seems to have had very little use. (There is no key with this case.)

The cord-and-wedge was used by railroad and Western Union telegraphers years ago to connect their personal bug to the company hand key on the operating table. The wedge end would be slipped between the base and connector strip of the hand key. A typical item (shown at right) has the old style cloth covered wires with integral stay-cord which was tied to one of the bug's wire terminals to prevent strain on the wires.

Very early (and occasionally later) Vibroplex C&Ws had no maker identification on them. But most Vibroplex wedges you will find do have the company name and address stamped on one or both brass leafs - as seen in this example. A wedge having an address that matches the nameplate on your key is a nice accessory.

Vibroplex-marked C&Ws we have are listed here. For those with no name, or another brand (especially Western Union) stamped on the leafs, see the main for sale page.

U.S. Shipping of a single cord is $3.50; no added shipping charge if ordered with a key.

Not all of our cord-and-wedges are shown here -- inquire if you are looking for a type not listed.

#CWV314 ... 833 Broadway cord and wedge.
Both wedge leafs are stamped with the 833 Broadway N.Y. address. While this particular C&W actually dates to 1944, it would be appropriate for a bug with a D5, D6 or D7 (1941 - 1979) nameplate.

833 Broadway cords are scarce. One terminal is missing part (see photo) but they attach to the bug wire terminals fine. Otherwise this cord and wedge is in very good original condition.

Address on wedge


#114MTY ... 796 Fulton Street, Brooklyn cord and wedge.
Both wedge leafs are stamped with the Fulton Street address. This would go nicely on a bug with the D3 or D4 Fulton Street nameplate (1925 - 1940). Red ferrule, black cloth cord cover. The stay cord is short (1") and the brass leafs need polishing, otherwise this is in very good condition.


#CW614BTE ... 796 Fulton Street, Brooklyn cord and wedge.
This dates to 1940 but would be appropriate for a 1925 - 1940 bug. It is in excellent unused condition, address on both leafs, light patina on leafs. (No photo.)
