U.S. Military telegraph keys

(J-38 keys are shown on their own page.)

Most of the keys that will be shown on this page are Army Signal Corps and U.S. Navy keys. Articles on military keys appeared in various issues of the Vail Correspondent (see the TVC index at another page on this site), and Larry Nutting's "J-Series Keys of the U.S. Army Signal Corps" (self-published, 1993) is a useful reference to these keys.

Most military hand keys from WWII are still relatively common and can be found at hamfests and on the internet. However, the scarce makes or models, and others in excellent condition, will command higher prices.

Some of the items are marked SOLD; I keep them on the page as an internet reference for collectors who are looking for a description, photo or information on the item.

U.S. Army Signal Corps J-xx keys

#815TYP J-2 key.

Here is a key that we hardly ever find: The Signal Corps J-2. This open circuit legless radio key is on a 5-1/2 x 3-1/4 x 1/2 inch Bakelite base. It has 1/4" silver contacts. This key was part of radio sets SCR 132, SCR-109-A, and SCR 159. The engraved legend on the base reads: SIGNAL CORPS US ARMY, ORDER NO 40416, TYPE NO J-2.

I do not know whether the terminals are original -- compare those on this J-2 key and on this Brach J-6. Note the common landline knob on the J-2 -- the knob on the Brach J-6 is said to be the original type and size used on both of these early Brach Signal Corps keys ... the knob on the key I offer here is the same style as on the J-6 but shorter. The terminals and the knob can be changed by the buyer (original parts or similar alternates show up on parts keys at hamfests and on ebay), so I leave it to the buyer to decide how he wants it to display. Finally, the white paint in the base legend is thin, you may want to refresh it (many various instructions for filling engraving can be found on the internet).

#037 J-3 key.

This key was used in a WWI field telegraph set; the lever folds to allow the cover of the set to be closed. It is all brass; the cast pivot frame is marked S193630. It has Fahnestock clips (another model had terminal nuts).

This key is all that remains of its set. It has been mounted on a piece of pine. The folding pivot and lever pivot are frozen. It is a display piece only.

J-4 key We have none at present, for photo see this page, no. 8235 (courtesy Tom Perera W1TP).

J-5 flameproof keys were made by several companies including General Radio, Western Electric, Connecticut Telephone, and L.S. Brach. All but Brach are scarce, but even with that maker there are scarce variations. Our J-5 keys follow:

#1003BAO General Radio Co. J-5 key.

This is a WWI era flameproof key. The top cover is engraved "Signal Corps US Army, flame proof key, type J5, date Mar 1 1918, order 41727 SC, General Radio Co."

GR is one of the scarcest makers of keys. Few models are known, all of which were made for the military around WWI. This is one of the scarcest of the scarce J-5 keys.
Very good condition. The lever appears to be polished, plated brass. A fine addition to any U.S. military key collection.

#514BGE General Radio Co. J-5 key.

As above. Good condition (that is a white stain nect to one mounting hole, it is not a chip). The lever is unpolished, plated brass.



#514MRY General Radio Co. J-5 key.

On this one there is a minor variation in the cover engraving: There are periods in the nomenclature "J.5." and the "S.C." -- compare the cover photos.

Very good condition. The lever appears to be polished, plated brass.

#205BRY Connecticut Telephone J-5 key.

A WWI era flameproof key made by Connecticut Telephone and Electric Company. Cast into the top cover in raised letters is "Signal Corps US Army, flame proof key, type J.5., date Mar 18 1918, order 41973, Connecticut Tel & Elec Co."

Military keys dating before 1920 are scarce. This flameproof key is in good condition; the cover and case finish show expected wear.

#0505BLL J-5-A WWII Western Electric flameproof key.

Cast on the round top cover is "Signal Corps, U.S. Army, flame proof key J-5-A" with order number 68-WF-42 and the maker Western Electric Co. Inc., Kearny, N.J. This scarce key is in very good condition.

#705DLY J-5-A WWII Western Electric flameproof key.

Cast on the round top cover is "Signal Corps, U.S. Army, flame proof key J-5-A" with the 1942 order number and the maker Western Electric Co. Inc., Kearny, N.J. It has a Signal Corps stamp on the bottom, and the knob is staked to the lever (first J-5-A I've seen like that). Excellent condition.

Another view.


The Brach J-5-A is the most common of the flameproof J-5 keys, and of these the 1941 Order No. 2670 is the most common Brach. (Click on the photo for a larger view of this cover plate.) Our Brach J-5 keys are below, including any we may have with a scarce cover plate.

#405BEP Brach J-5-A key.

This has the 1941 contract date plate. Very good used condition. Unusual grayish finish on lever arm and connector terminals. Needs cleaning.

SOLD -- inquire as we occasionally obtain others

#399BTG342 BRACH J-5-A key.

I found this at a hamfest in Arizona a dozen years ago. With its feet and bottom label, I suspect it was a presentation item (perhaps to the General who awarded Brach the contract?). It is in excellent, unused condition and only shows a bit of age patina on the cover.

Bottom view.


#410BEY 1942 BRACH J-5-A.

A rare Order No. 583 Brach J-5-A dating to 1942. Very good condition; Signal Corps number stamped on bottom.

$129.00 each (S&H = $8.00)

J-6 key The J-6 was, I believe, an early (pre-WW1 era?) aircraft key. It has a typical British-style pull-down spring on the lever behind the pivot -- and interestingly, one I have seen has what appears to be the British "arrow" stamp on the bottom. The key shown at right was made by Brach.

None available at present.

J-7 keys: The J-7 and J-7-A are J-5 type Army Signal Corps keys with the addition of a "winker light" on the 2-1/2" x 5-1/2" phenolic base. These early and scarce J type keys were used in aircraft during and after World War I. The light provides feedback to the operator in the noisy environment. In some applications two keys were attached to the radio; the winker allowed the observer to see what the pilot was transmitting. The hood is removable. When found the bulb is usually missing; any D.C. bayonet base bulb may be used for display purposes (see the note on Navy winker keys near the bottom of this page).

#410KGY J-7-A by L.S. Brach.

The top cover reads "Flame Proof Key, type J-7-A, date 1921, order no. 141082, mfg. by L.S. Brach Mfg co, Newark N.J."

This key is in very good cosmetic condition, it may be new-old-stock.

As usual for these keys, the bulb is missing. An automotive type bulb may be used for display purposes.

J-8, J-9 keys. Believed never issued, nomenclature not used. (Information from Larry Nutting's (WD6DTC) book J-Series Telegraph Keys 1993).

#512CBC J-12 key.

The J-12 was a general purpose open-circuit key (no circuit closer) intended for low-power radio use with, for example, the SCR-109-A (BC-86A) and the the SCR-79A (BC-32A). It is a solid brass key similar to the Western Electric / ATT keys, but with huge 1/4" contacts (see photo). This one is mounted on a brass plate as removed from equipment.

This scarce key is in good condition and would be a great mil-spec key for amateur use. The spring is a replacement.

Legend on key.


#408CBB J-30 key by Brach
Made by L.S. Brach, as indicated by the "B in a diamond" logo stamped on the main lever. The only keys made by Brach were made for the U.S. military during and after WWII. This is the J-30 closed circuit key for general purpose application. It is basically identical to the key used on the J-38 assembly.

(The only Brach J-38 I have had was a little different -- see no. 711CTH on the J-38 page.)

This scarce key is in excellent, like-new condition. The only marks are on the circuit closer, which shows it has been closed once or twice.


#406CTE J-30 key by Signal Electric.

The J-30 was a general purpose closed-circuit key (i.e. with a circuit closer). It is the same style key as used on the J-38 Bakelite base. The key here was made by Signal Electric Company, as shown by the cast "1852" under the base. This is an early one as indicated by the U.S.S.C. stamped in the base, and the conical wire terminals (see this page for the Signal Electric variations).

This is in good operating condition with all original parts but for the spring, which is a replacement. Polish the brass, buff the steel lever, and you will have a fine collectible.

The J-36 key was the Army Signal Corp's semiautomatic key, or bug. Collector Tony Rogozinski, W4OI, reports that the Signal Corps used olive drab painted Vibroplexes in the late teens and early twenties, though the earliest J-36 keys marked as such were made by Brooklyn Metal Stamping Corp.

Later, the Signal Corps would award contracts to others for the J-36. Judging by Rich Dailey's (N8UX) J-36 Bug Census Project, the earliest Vibroplex is 1936, and the Lionel and Bunnell contracts were awarded in 1942. The use of a stock Vibroplex as the J-36 would come full circle after WWII.

The Brooklyn Metal Stamping J-36 is the scarcest J-36, with Lionel being the most common. Bunnell and Vibroplex fall in between. This ranking likely reflects the number of keys produced under contract to the Signal Corps.

The Brooklyn Metal Stamping Corp. J-36 is the earliest J-36 with that nomenclature on the nameplate. An original box in W4OI's collection is marked "Telegraph Key Vibrating, Signal Corps Type J-36, U.S. Army Spec No. 71-291-A, Order N. 3774-N.Y.-30, June 10, 1930."

Only five or six of these bugs are known. No serial numbers appear on the nameplate, but based on the few known keys, the 1930 order was the only contract awarded to this company, which would account for the scarcity of this make. And it seems to have become surplus rather quickly; an ad in the ARRL Radio Amateur's Handbook for 1932 by Uncle Dave's Radio Shack offered "Signal Corps Bugs Similar to Vibroplex," the price was "$9.65/NEW." These were likely Brooklyn Metal Stamping J-36s.

The BMS J-36 or "Speed-Bug" as it is called on the nameplate has a couple of unusual features. To quote from Randy Cole's website, "the BMS J-36 included several novel features. The damper is not a wheel, but a captive [and spring loaded] ball bearing inside a slanted tube, the dot spring is mounted on the dot post, not on the lever, and the circuit closer pivot is directly under the vertical pivot." It also has an unusual cast iron base in that the damper, nameplate, pivot frame, fixed contacts and wire terminals are situated on raised lands. Very few bugs have raised features on their bases.

Any BMS J-36's we have will be listed immediately below.

#113TRE Brooklyn Metal Stamping J-36 bug.

Brooklyn Metal Stamping Corp. Signal Corps J-36 bug, described above. This one is NOT in original condition -- non-original parts are: the wire terminals, one foot, the pendulum weight... and perhaps a few other parts. The U-shaped dot spring is missing from the fixed contact screw (a Vibroplex type could be soldered on) but I did get it to work with critical adjustment even as shown. There are some chips in the base paint, there is an added hole in the base and red-painted letters (see photos).

This is, as shown, a display key, but with some work could be made better looking and better operating. If you collect bugs or U.S. military keys, here is an opportunity to add what is perhaps the scarcest Signal Corps key to your collection.

#309TEO Bunnell J-36 bug.

(Click on photo for a larger view.) Army Signal Corps J-36 by Bunnell. This has a 8-4-42 contract date and serial number 2556. Signal Corps stamps are seen on the bottom.
The Bunnell J-36 is scarcer than (and quite different from) the Lionel and Vibroplex Signal Corps bugs. The pivot frame on the Bunnell J-36 has an interesting shape (reminds me of an old Packard grille).
The weight is unplated and may be a replacement, and there is a 1/4" chip in the finish near the back (see photos). Otherwise, this is an original, complete bug in very good condition.

Bunnell bug cases (if we have any) will be on this page.

The Lionel J-36 was made by the Lionel Company for the U.S. Army Signal Corps during WWII and is quite similar to that made by Vibroplex (some say Lionel made them under contract from Vibroplex), patterned after the Lightning Bug model.
The nameplate Unlike other J-36 bugs, the nameplate on the Lionel was made of celluloid plastic. Over the years, most of them shrank and pulled away from the (five) rivets holding it to the base, and broke off.

If you wish to replace your missing nameplate, Tom Perera (W1TP) has provided a copy on his website which you can reproduce; click here and scroll down to item #7935; this nameplate has serial number 13424. Nice reproductions have also been offered on ebay with serial number 13439. Keep in mind that if you find a Lionel J-36 with a nameplate bearing one of these serial numbers, it is likely a reproduction nameplate.

#L1007BGR WWII Lionel J-36 bug.

As above; the nameplate has shrunk and separated at one end. Original ones even in this condition are scarce, so you may want to leave it.
The tops of the wire terminal nuts seem to have been polished and clear-coated. Apart from this, and the nameplate, this bug is in very good, original condition.

The Vibroplex J-36. The WWII semiautomatic key made by Vibroplex for the Army Signal Corps was the military version of the company's Lightning Bug. These are somewhat scarcer than the Lionel version. They have a metal nameplate which occurs in several variations: small and large pre-WWII Fulton Street plates, and two WWII small plates with either Fulton Street or 833 Broadway addresses.
Each plate includes the order number and date, as well as a stamped serial number. Many of the Vibroplex J-36s used for Signal Corps Morse school training will be found with a mounting hole drilled in the base (between the pivot frame and nameplate) and an inventory number painted on the front edge of the base (facing the operator).
Well after WWII, only Vibroplex supplied semiautomatic keys to the military. These were stock keys stamped on the key or the box with the contract information; they carried no special nameplate.

#707BHT Vibroplex J-36 bug.

This "old school" J-36 was used in classroom training: It has a Signal Corps key number 120-7 on the front edge, and the usual hole in the base (under the mainspring) for securing it to the school desk. It has a red Signal Corps stamp "SC120A" on the bottom of the base. The steel nameplate carries a June 6 1941 date and serial number 1215.

This key is complete, original and in very good condition, with an excellent nameplate. It is a nice representative example of the bug as first seen by RO trainees.

Another view. ... Nameplate.


#514BGO Vibroplex J-36 bug.

This J-36 was apparently intended for use in classroom training: It has the usual hole in the base (under the mainspring) for securing it to the school desk. It has a red Signal Corps stamp "SC120A" on the bottom of the base. The steel nameplate carries a June 6 1941 date and serial number 2117.

This key is complete, original and in very good condition, with an excellent nameplate.



#1213CGR Vibroplex military bug.

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 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, and has the lever and upper pivot screw protective rubbers as shipped from the factory.

A note on the J-37 key. The J-37 was a general purpose open circuit (no closing switch) radio key; it was used on the BC-148, on the control box BC-177, and on several other sets.

Mounted on a Bakelite base, ten keys were used in the AN/GSC-T1 code training set.
It was also mounted on a leg clamp and became a J-45 (later called the KY-116/U) for mobile radio use. With a different cable it was the KY-872 used with the PRC radios.

#M0411JCB Winslow J-37.

The ubiquitous J-37 hand key, used on various bases to create other J-xx key types. This one is stamped "Winslow Tele-Tronics Inc 66150" on the main lever. It is in excellent, unused condition.


#J37ANGSC Signal Corps J-37 on base..

This key is a J-37 in an "I" shaped Bakelite base. This model, a J-37 on the unique Bakelite base, does not have its own military nomenclature. Ten of them were included in the lid of the AN/GSC-T1 code training set. Each key had its cord wrapped around the base (the reason for the indents on each side).

This one is new-old-stock, unused, and still has its original, unwrapped cord.


#J37N156 Signal Corps J-37 on base..

This key is a J-37 in an "I" shaped Bakelite base. This model, a J-37 on the unique Bakelite base, does not have its own military nomenclature. Ten of them were included in the lid of the AN/GSC-T1 code training set. Each key had its cord wrapped around the base (the reason for the indents on each side). Very good condition, though the cord is missing.



The code training unit mentioned above, without keys. The oscillator is mounted in a heavy military style carrying case with handles, measuring about 18 x 11 x 14 inches high. Several manufacturers made these for the Army Signal Corps, this one was made by McElroy Manufacturing Corp.(McElroy was the world champion radio telegrapher and the maker of the collectible Mac-Key bugs, prior to WWII). These units operate on several DC and AC voltages (selectable). Complete instructions are on the engraved metal plate on the front panel

It is original and in excellent cosmetic condition. Electrically tested on 115 VAC and working, in both the audio oscillator and the neon blinker modes. The photo here is a typical complete unit, not the one offered, if you are interested request actual photos.

$145.00 plus shipping of $45.00 insured Fedex ground in the lower 48 states.
Special: This unit plus one NOS J-37 on base, $179.00 plus shipping.

J-38 keys, see this page.

The J-41 key.
This is a scarce key since it was used on only one device, the TG-5 (and TG-5A, TG-5B) field signal telegraph set. It has both normally open (front) and closed (rear) contacts, and has a third binding post near the tension adjustment screw. The wire terminals are: Front right, front (NO) anvil contact. Rear left, back (NC) contact. Rear right, main lever (common).

A 1944 Winslow TG-5B unit (CAKU maker code) has been found with a factory-modified J-37 key. This J-37 (so marked) replicates a J-41 with a closed contact added at the back of the key, with the NC wiring direct to the contact (a common screw). This may demonstrate the exigencies of wartime.

The J-41 model was used in the TG-5 and TG-5A sets. The J-41A key used in the TG-5B set differed in that is "has a raised platform underneath the rear contact. This is to prevent dust particles from creeping underneath the rear contact, separating the contacts and thereby opening the line" (as stated in Technical Manual TM11-351, issued 1943).

Any TG-5 sets we have will be listed below after the keys, under Signal Corps Misellaneous.

#413CCA Signal Corps J-41-A.

Description above. Used, complete. A wire was soldered to the anvil terminal; clean that up (if you wish) for a good looking scarce military key.

A nice addition to your collection, or use it to restore that TG-5 set!

#J43N151 Signal Corps J-43..

This general purpose key is composed of a J-37 on an engraved Bakelite base. It has a toggle switch which connects the contact to a "relay" terminal. No manufacturer is indicated. This scarce key is in very good condition, complete and original.


#711BLT Signal Corps J-44..

This key was used with radio sets SCR-178 and SCR-179 (BC-187). It is composed of a J-37 on an engraved Bakelite base. It has a slide switch marked "voice" and "tel" which shorts the key terminals (it is like the old landline circuit closer lever). This key was made by and is marked E.F. Johnson, well known as the manufacturer of the "Viking" line of amateur radio transmitters (remember the Ranger ?) after the war.

Good condition, tested and working, needs cleaning, some wire covering missing on bottom, number scratched on bottom, patina on metal parts.

#811DOY Signal Corps J-45.

"Real" J-45 keys are getting harded to find (the later KY-116/U is more common). Here is one, well used and showing it, but complete (except for a cord) and original.

#911BLR Signal Corps J-45.

This appears to be a late J-45, the nomenclature is stamped in ink on the leg clamp. It is in very good condition, possibly unused, and includes the CD-201A cord with PJ-055B plug.

#210BEG Signal Corps J-45 type key.

This is a KY-872, which is essentially a J-45 with a cable for PRC radios (74, 104, etc). This has a J-37 key on the leg clamp, and a CX-11468/U cable (marked 755002A1001) which is terminated in a U-229 five-pin Signal Corps connector.
This is new old stock in its original paper wrap (may be opened one end) dated 1993.

#U606CAT Winslow J-45 TYPE with J-47.

This is very much like the Army Signal Corps J-45 or the KY116/U leg-clamp key, but on this rare variation a J-47 slides into a holder on the leg clamp. (Will not slide out, at least not easily, perhaps after 60 years of being installed.) The Winslow logo is stamped onto the steel leg clamp. The J-47 has no maker's mark. It folds up just like the more common J-45. The only one of this style I have found in twenty years of collecting. A superb item for the US military key collector who wants a complete collection.

A German military version of this key is shown on this page.

The J-46 key is a simple strap key on a 2 x 4 inch Bakelite base. It was part of the WWII Signal Corps EE-84 portable field signal lamp set which includes the M-132 Signal Light. It is one of the very few Signal Corps keys that does not have its J-type nomenclature marked on it, and usually has no manufacturer's identification. Based on NOS keys found in their box, they were provided by Maurer and by Winslow, and perhaps other contractors.

#1112BLE WWII J-46 key.

This J-46 was made by Maurer, as noted on the box label. It has a nice Signal Corps stamp on it. The original box is dated 1942. The key is in NOS condition; the box is rubbed on the edges.

The J-47 radio key (no circuit closer) is a nice hand key for amateur radio use. Because it is mounted far back on its base, it will not tip when used. There are at least four variations. The most common is a J-37 on a flat, engraved base. There are also a J-37 on a cast base, a Lionel J-38 (without its circuit closer) on a flat engraved base, and the Lionel on an engraved Lionel J-38 type (rounded corner) base. The J-47 (especially one of the Lionel variations) makes a nice ham radio hand key.

#L407CTT Lionel J-47.

Here is a scarce Lionel J-47 key. It is the same hand key as the J-38, but without the circuit closer and on a J-47 marked base (with a red Signal Corps stamp). This may have been assembled by a third-party vendor, as the base is not the usual Lionel type (or perhaps Lionel bought the bases "out of house"). The key shows age: the main lever has lost most of its plating and is tarnished. Otherwise it is all original.

#307CLA Lionel J-47.

(Click on photo for a larger view.) Army Signal Corps J-47 by the Lionel Corp, known better as the maker of model railroad trains. This uses the same Lionel key as the J-38, but without the circuit closing lever. It also uses the same basic Lionel Bakelite base ("L" variation), but drilled and etched for the J-47. This is a rare find. Very good condition, complete and original. Bottom photo.


The J-48 key.

For information only.

Here is a photo of a J-48 key made by Signal Electric Manufacturing Company, with its original box apparently dated 1945. Click on the photo to see the box label enlarged. This is an interesting key, in that the lever is insulated from ground, the lever has an insulating sleeve, and it comes with a "Navy" type knob. Apparently the BC-654 put a lot of juice on the key.

The aluminum base on which this one is mounted seems odd -- perhaps someone mounted it on their own base for display, though I can't say for sure since this is the only such boxed key I have seen. Larry Nutting's (K7KSW) book on J-Series keys does list the J-48 (complete with base and cover) as a Stock no. 3Z3448, as stated on the box. I have found no other application other than the BC-654 for the key itself (see below).
This key is one of those used on the J-48-A; the other is the J-37 (not listed as a J-48 key in Larry's book).

#310COY Signal Corps J-48-A hand key.

This is the key that clips inside the cover of the BC-654 receiver-transmitter (part of SCR-284). The base is stamped J-48-A (under the knob). It is comprised of a hand key with skirted knob, on an aluminum base with an aluminum cover. This one has the scarce brass key.

The keys used for the J-48-A were either a Bakelite-based J-37, or the scarcer insulated contact, brass-based J-48 key seen here. This is the only application of this unusual key that I am aware of.

This is in good working condition but needs cleaning, and the key lever is oxidized. One (of the two) cover retaining screws is missing. The long 4-foot cord and plug do not appear to be original.

#1107KY605U modern Signal Corps mobile key.

This is a KY-605/U key; it has velcro straps, and is made to be strapped on the thigh for mobile use. This particular key was made for the Signal Corps in 1977 by Electro-Voice, Inc. The key is similar to the J-37 degign, using a leaf spring under the lever. Most of the parts are high-impact plastic. It has gap and tension adjustments. The straps may be removed if you would like to use it on your operating desk. Overall a very modern military straight key. Condition is new-old-stock, unused, in the original packing.

Signal Corps WWI trench transmitter

This is a Signal Corps portable spark transmitter marked SCR-74-A, made by American Radio and Research Corporation (AMRAD), New York NY and Medford Mass. (Reference BC-18A.) It has the instructions and schematic in the lid, and an original paper tag attached (not filled out) with AMRAD's Medford Hillside address. This consists of an induction coil, spark gap, battery meter and telegraph key. The large terminals on the left marked ANT and GND and are for attaching the antenna and ground to the set. The compartment on the right is for the 10 volt battery. There is a rubber cover so that the telegraph key can be operated with the lid closed, and two mica windows in the lid for observing the spark gap and the amp meter. Additional information is on this PDF page.

This military wireless set was designed for reporting from the trenches as described by Capt. A.P. Corcoran, "Wireless in the Trenches," in Popular Science, May 1917, pages 795-799: "The wireless, as I have said, is now an essential part in all trench warfare. When the infantry adavances to an attack, the operator is always slightly to the rear. Where formerly a detachment of men had to reel out hundreds upon hundreds of yards of cable to establish telephone communication between a trench newly taken from the enemy and the first line reserve behind, now the operator simply picks up his box, his ground mat and his aerial singlehanded and advances simultaneously with the attackers. Arriving at his new position, he props up his aerial, lays his ground mat and communications are established almost at once. It would be hard to overestimate the importance of his duties. When an enemy trench is being taken, it is he who reports the progress of the encounter-- the number of the enemy, the nature of their defence, the amount of the casualties on either side, the condition of the trench when it is finally taken-- whether it has been badly damaged by artillery fire, or whether it is practically intact. If a gas attack is coming, it is he who sends the warning to the men behind to put their gas helmets on."

This particular set was probably made after the end of the war, around 1920 or so. It appears original and complete and in good condition, with the exceptions that there is no battery and the web carry strap is broken. The case is about 11-1/2 x 12 x 6 inches. It weighs 20 pounds. A scarce addition to your early wireless or military radio collection.

#M907TEO Signal Corps EE1-A buzzerphone telegraph Set.

This is a WWI wire telegraph set for field use. It was made by Western Electric and is dated 1919. It is a compact and fairly small unit; the wooden case measures about 9-1/2" x 6" x 6-1/2" high.
The EE1-A buzzerphone was developed for secrecy in field communications, and avoids message interception by ordinary induction methods or methods using leakage current to ground. It is a wire transmitter / receiver (one side of the line may use ground) using very low direct current, about 60 microamps. The telegraph key is marked "4A" but it is not a "J" type key.
At the receiving unit, a "howler" (two microphone buttons and a headphone earpiece) modulates the signal so it can be heard in the receiving operator's earpiece. The howler in the sending operator's unit provides feedback (sidetone) to him.
This rare unit shows age but is complete except for the earphone, batteries and carrying strap. The outer nameplate is good, and the metal corners, latches, and strap brackets are present and good. The operating instructions and schematic inside the cover are very good. The metal ID plates (send/receive, potentiometer, and manufacturer) have lost some of their finish. The earpiece clip is still present, as are its wires. The key has all its parts and works well. The unit does need some cleaning and its electrical operating condition is unknown.
Add a vintage headphone earpiece and this would make a great item for WWI re-enactments.

#M1107BGA Signal Corps EE1-A key.

This is the 4B key from a WWI buzzerphone telegraph set (see above). It is mounted on a Bakelite base with a wood sub-base. It is so well done that it looks like it came this way.
The key has its front and back contacts brought out to wire terminals; the center terminal is common (key frame). It works well and can be used on the air.

#M907CDB Signal Corps WWI telephone handset.

This is a WWI field telephone handset. I do not know its nomenclature or what system it goes with. It is stamped in red "SC 1285P" (?) and "19-C."
It is complete with its cord and clips. There is some corrosion on the back plates, and it needs cleaning. The receiver and transmitter caps unscrew easily.

#911COY Signal Corps TG-5-B Telegraph Set.

This is a WWII telegraph set made by the Winslow Company in 1944. The TG-5 series contained the only application of the J-41 three-terminal Signal Corps key -- however the key on this unit is a rare factory-modified J-37 (marked J-37 with the added third terminal at the back). This unit does not have the "Winslow" name on the namplate, but is identified as Winslow by the CAKU order number code and is dated 1944. It has the often missing burnisher tool, and an R-14 headphone made by Consolidated Radio Products (which has an MS-162-A cushion on it). The headphone does not have a headstrap; the cord has the usual PL-55 plug.

This is in average used condition: There is oxidation on the top cover, and OD touch-up paint around the front and back case screws. The battery compartment at the back is clean. It is electrically and operationally untested.

#165 TG-30 hand key.

This key, with its Bakelite base, was removed from a TG-30 telegraph / teletypewriter repeater set. This steel lever key has a solid brass frame and hardware. The black-finished frame has "P0582B" cast into it. It is one of the rare military keys with a back contact (another is the J-41). Solder connectors are on the bottom. With its large radio type contacts, it would make an excellent ham radio key.

#2H101 $149.00 (S&H = $5.00)

I am indebted to Rob Flory, K2WI, for information on some of these Navy keys. You can see his website on WWII Navy Radio here (and click on the link on that page).

U.S. Navy bugs. Unlike Army Signal Corps bugs (J-36), Navy bugs are scarce. Few were "liberated" by radio operators. Some were made to special order by companies like McElroy and Bunnell and had "property of U.S. Navy" cast into the base. Those provided by Vibroplex were standard models (usually the Champion) and were stamped on the bottom to identify it as a Navy key.

Any Navy bugs we have for sale will be listed immediately below.

#1112CHG Navy issue Vibroplex bug.

This 1952 Vibroplex Champion (serial number 176xxx) has the Navy stock number N17-K-45926-1001 stamped in red on the bottom. These early 1950's military bugs are mentioned at page 73 of the Vibroplex Collector's Guide (third edition).

This is in excellent condition, possibly NOS unused. As a nice Champion, it is a great key to use on the air. As a vintage U.S. Navy bug, it is also a fine military collectible.

#308TPL Bunnell Navy bug.

Here is a project for the restorer. The metal nameplate reads "manufactured by J.H. Bunnell & Co" and cast into the right side of the base is "property of U.S. Navy." Notice the large "radio" contacts and the unique Bunnell damper and pivot frame designs.

The base finish is excellent, as is the chrome on the upper parts. It is missing: weights, pendulum dot contact, dot and dash springs and hardware (see photos). The fixed dash contact screw head is broken and missing. I will include a replacement paddle (original type) and a knob. The connector strips on the bottom have been replaced with a piece of PC board.

You might obtain replacement parts from a more common Bunnell Signal Corps J-36 or parts from other bugs (Vibroplex etc) might fit. Finish it up and you will have a rare Navy bug.

#913BOP Navy bulkhead blinker key.

This rare key is based on the Army Signal Corps J-38 in its use of the phenolic base (with its three mounting holes, even though one is covered by the nameplate), the key, and the wire terminals.

The metal nameplate reads: "Bureau of Naval Personnel, Bulkhead Blinker, NAVPERS 40008, procured through Office of Naval Research, Special Devices Center." This key was likely used as a light signaling key and/or a training key (similar to the Navy JK-38, see our J-38 page).

This is in very good original condition. The plating on the main lever has some oxidation, and the top surface of the phenolic base looks as though it was polished with 80 grit sandpaper ! (That makes me wonder if these used J-38 bases with the engraving sanded off.)


$129.00 (S&H = $8.00)

#798GYY Navy SE-68A spark key.

This Navy leg key dates to the early 1900s. The brass nameplate identifies it as an Auxiliary Hand Key, type SE-68A, made by the machinery division of the Boston Navy Shipyard. The base appears to be Bakelite, and measures about 2-1/2 x 5 inches. The legs are about 2-1/2 inches long. The huge contacts are about 5/8 inches in diameter to handle the 250 volt, 50 ampere circuit (as stated on the nameplate).

This key, which has been in my collection for 15 years, is in very good original condition. The plastic stand is not included.

$749.00 (S&H = $12.00)

This is a simple straight key with a circuit closer and a heavy solid brass base. The base is heavier and more solid than that on the the Army J-38 (J-30) key, and so the 26001 key makes a great amateur radio desk key for CW work.

#901CTY Navy 26001 straight key.

U.S. Navy radio hand key made by Signal Electric Mfg. Co. Steel main lever, brass base. It has a SEMCo no. 1852-A cast in the bottom of the base, and the Navy nomenclature CSE-26001 stamped into the top of the base. Shows use and age but in overall good condition.

#615BEA Navy 26001 straight key.

U.S. Navy radio hand key made by Lundquist Tool & Mfg. Co. of Worcester, Massachustss. Stamped C.L.T. 26001-B on the steel main lever, the solid heavy base seems to be plated brass.

The wire terminal screws are not identical, one has a shoulder on it. Obviously used and needs cleaning (it looks lke the previous owner started on the main lever). A nice, heavy, solid hand key made to US Navy specs.

Stamp on lever.


#M0411JCA Navy model CLT26012A hand key.

This key was made by Lundquist Tool Co. (code CLT). It is unusual in that it is completely insulated. The base and terminal caps are bakelite; the lever is insulated from its contact. The left pivot support is marked GND and has a screw for directly wiring the supports and lever to system ground. At the left side of the base is a slot for a bug wedge. All of the metal parts are brass. Very good condition.

This key was used on the Navy 23146 control panel; it may have also had other applications. Being completely insulated, it is sometimes found with a metal (instead of Bakelite) knob.


#M1206KJC Navy button key

This little (1-3/4" square) key has no model identification on it, but others have the Navy nomenclature CAY-26013 stamped on it (the maker "CAY" is Westinghouse Electric). It was for the Navy TBY transmitter-receiver. This key has mounting screw tabs, and also a clip on the bottom. Originally this key would have a thin rubber cover, but most of them have been lost due to age and wear. The cord has been cut off; otherwise it is very good with no chips or dents. Scarce.


Note, the TBX and TBY radios were used by both the Navy and Marine Corps.

waterproof Brelco leg clamp key.

This sealed key was made by Brelco, and bears the Navy nomenclature CAQZ-26026 which indicates manufacturer (CAQZ) and key type (26026). It is for a Navy TBX-8 transmitter-receiver. The key can be worn on the operator's leg with the clamp, or removed from the leg clamp and mounted on top of a TBX radio. This one comes with the scarce leg clamp; it is in excellent condition, with the original cable and PL-55 plug.
Second photo.


#810BER Bunnell Navy straight key.

This is a Navy type CJB-26001A hand key on a clip-type base; it is for a TBX through TBX-6 transmitter-receiver, and mounts on top of the radio as shown on this TBX. (Also, it may have been used with a leg clamp.) "401" stamped in red on the cable clamp.

Used condition as shown. This is a nice item for the Bunnell collector, and an unusual ham radio key, with its large "radio" contacts.


#408CAY Waterproof key.

It is rare to find one of these with the rubber waterproofing boot intact. I believe the key under the boot is a 26001 type hand key. Although the boot feels fresh and supple, I don't want to try to remove it and chance damaging it. (K2WI says the boot makes it really hard to adjust; when it was new it was probably not too hard to remove the boot to adjust it, but for an old key he wouldn't dare.)
This was used with a TBX through TBX-6 transmitter-receiver, and mounts on top of the radio (such as the one shown in this photo). It may also have been used with a leg clamp.
Additional information from an article in Morsum Magnificat no. 22, Spring 1992, by Hugh Miller KA7LXY, who wrote that this key "is part of a US Navy set, TBX-8, which was a 2.5 Mhz portable unit for use by landing parties from beachhead to ship. With its waterproof case closed, the set could be floated to shore then then be opened ready for use."

The stamp on the bottom (a T inside a diamond) is a Navy stamp, and is found almost exclusively on equipment used by the Marine Corps. Here is a great addition to your U.S. military key collection.

Navy 26003 key.
This flameproof key was made for the U.S. Navy in the WWII era. It was used for yardarm and signal lamp purposes (it may also have had other communications applications). The key is completely sealed, with external adjustments for contact gap and tension. This rugged key includes a "Navy type" knob and a protective plastic cap over the wire terminals (often missing or broken).

Some of these keys are found on a housing containing a large capacitor; some have a warning on the knob disc "do not close over 2 min"; some have an additional warning attached "do not use for illumination" (the lamp it controls is for signalling, not for lighting purposes). These keys were made by several manufacturers. Some known makers of the 26003A and their manufacturer's code are J.H. Bunnell (CJB), Molded Insulation Company (CMI), and D.P. Mossman Inc. (CDM). Although it is said to have been intended for lamp signalling, many Navy operators considered the 26003A to be the best hand key for sending Morse.

Any we have are listed below.

#514MOY Navy flameproof key..

This is the basic 26003A flameproof key; the CMI designation identifies it as made by Molded Insulation Company. This is in excellent condition, with no chips in the paint finish or the plastic terminal cover.

Navy signal lamp key.

This rare waterproof key-and-capacitor assembly was used on a ship for yardarm light signalling. It is a 26003 key (unusual in that it is not marked) mounted on a sealed capacitor. While the nameplate says "General Electric Signal Key," the nomenclature (CMI-26003A) on the nameplate indicates this device was made by Molded Insulation Company. The key disc is marked "do not close over 2 min" and a plate on the capacitor reads "warning, do not hold key closed for illumination purposes, U.S. Navy."

#804KM1 Navy Signal Key.

This is a Navy ship's "signal key with capacitor" made by Westinghouse. It is used, I am told, to activate yardarm signal lights. It incorporates a CMI-26003A key (made by Molded Insulation Co.) and a 2 Mfd capacitor in a weatherproof cast aluminum housing. The nameplate is dated 10/52. The plate is a bit faded, but otherwise this is in excellent condition and appears never to have been placed in service. Second photo.

Shown for information only; click on the photo for a larger view. This is a simple hand key without a circuit closer on a wooden base. Note the Navy anchor stamp on the base above the knob, and the nomenclature CJB-26021 below the knob. The CJB code indicates this one was made by the J.H. Bunnell Company.

Here is a CJB-26021 in better condition. Top view, note Navy anchor stamp. (Photos courtesy of Bob, KD2UJ.)

#RM-28 key cover, with key.

This rarely seen Bakelite cover measures 3-1/2" in diameter and 1-1/4 inches high. The decal on the top reads "key cover, type RM-28, Radiomarine Corporation of America." These keys were used used on the RCA 4U through 6U shipboard consoles (found on many Victory ships in WWII) to protect the RO from the high voltage present on the key contacts; see, for example, this 4U console. This item includes an original Signal Corps J-37 key. The cover is in fine condition; the decal is worn.

#1210CGY Navy Morse key panel.

This SB-315 B/U Morse key station panel is complete and original. These units were mounted flat on the radio station desk, and had a protective metal box underneath the panel. The metal data plate indicates it was "for general electronics use" made for BuShips by Dittmore-Friemuth Corp. of Milwaukee, Wisconsin. The Bakelite plate measures 5-1/2 x 6-3/4 inches and includes a Navy flameproof key, toggle switch, jack for semiautomatic key (bug), and indicator lamp. The plate is in very good condition with only minor dings.

The Morse key has gap and tension adjustments on top. The sealing gasket on the lever is aged and broken. The key case may have been repainted at one time (there is paint on the gasket), but is the correct original color used on this model.

What is presumably the earlier version of the above panel, the SB-315 A/U, had a somewhat different key on it -- see this photo courtesy of K4NYW.

#213CLG 23116 Navy control panel.

This is a model CRL-23116 control panel. The Bakelite plate measures about 5-1/2 x 6-3/4 inches. The CRL code suggests it was made by Remler (two companies had the same code) and the 23116 number on the engraved nameplate suggests a post-WWI era item. It incorporates a CJB-26012A insulated key made by Bunnell, which has a metal knob (sometimes found on these keys).

This rare panel is in average used condition; the lamp bulb is missing, and the Bakelite plate could stand polishing.

#1106CTY NAN sytem key

This plate was apparently mounted on a box or panel. The circular brass part is marked "Manual key for X-3A NAN system;" the steel plate is stamped "PNY" and "S6700-696055." The plate has a lamp adjustment knob for bright and dim. The Key arm is soldered to a flexible brass plate which is sealed from the bottom apparatus. Underneath are the large, heavy current contacts. My guess is that is was a yard-arm lamp key. Second photo. Third photo.


#0204BOL yardarm light key

This unusual and scarce Navy ship key was mounted on a sealed enclosure and so was of the "flameproof" type. It is said to be part of a ship's infrared yardarm light signalling system for signaling at night under darkened ship conditions. Stamped next to the indicator lamp is "AN/SAT-2 monitor." The key incorporates a locking or circuit closing lever. The brass plate is about 6-3/4" in diameter. Since it is from a ship, this is one key that could appropriately be polished up and be a sharp addition to any collection.

NEW INFORMATION: See this page which describes the use and shows a photo of the key.

Navy winker light keys.
The 1140 and 1213 keys are a Navy version of the Army Signal Corps J-7 (see above). They have a "winker" bulb, but are usually found with the bulb missing. I have found two 1140 keys with bulbs -- one had a no. 82 bulb (6.5 volts, 1.02 amps), the other had a no. 88 bulb (6.8 volts, 1.91 amps). I don't know whether either of these is correct for the key, but any bulb with a double contact candelabra bayonet (or D.C.bayonet) base (#BA15d) will do for dusplay.

#082 Navy CQ-1213.

The metal plate on the lamp cover of this rare key reads "flame proof key and winker, type CQ-1213, serial no. 4518Q, International Radio Telegraph Co." The cover of the key is engraved "airplane flame-proof radio key, type CAG-1159, made for Navy Department, Bu. of S.E., General Radio Co., Cambridge, Mass." (The Bureau of Steam Engineering had jurisdiction over telegraph keys for the Navy.) This is complete and original (except for the lamp, missing as usual); the lamp base finish is chipped; the key cover plate has some oxidation - freckling; and the key lever is slightly bent.

#U306TPP Navy CQ-1140 .

The metal plate on the left side of the base reads "flame proof key and winker, type CQ-1140, serial no. [blank], International Radio Telegraph Co."

These keys were used with aircraft spark transmitters powered by a wind-driven generator, such as the 200 watt CQ-1115; a diagram of this transmitter can be seen on this page.

This is complete and original (except for the lamp, missing as usual). The key cover is scuffed, there is some scufrfing on the lamp cover, and the knob seems to have a bit of heat damage.
