NOTE ON THE DATING OF VIBROPLEX BUGS:
John Elwood, WW7P has been gathering information about Vibroplex keys for many years. He has been able to reconstruct many of the dates of manufacture of the various models of Vibroplex keys which had been lost in the Vibroplex fire. His complete list of dates is published in the Vibroplex Collector's Guide by Tom French W1IMQ which is listed in the bibliography section of this website. You may also find John Elwood's complete list by going to the website of Randy Cole KN6W at: http://www.la.ca.us/frandy/dating.html
The following information briefly summarizes these published findings. To use this summary, first find the serial number on your Vibroplex. It will be stamped into the label on later models and into the damper or other parts on early models. Then use this table to find the approximate date of manufacture:


Serial # Date Serial # Date Serial # Date 001,000 - 1905 150,000 - 1946 040,000 - 1980 (Portland ME) 010,000 - 1911 200,000 - 1957 060,000 - 1988 050,000 - 1914 250,000 - 1967 080,000 - 1995 (Mobile, AL) 100.000 - 1920 300,000 - 1974

7075 DOUBLE-LEVER DUNDUPLEX BUG WITH RARE ORIGINAL METAL CARRYING CASE:(36KB) This is a double lever Dunduplex bug with the rare metal Dunduplex carrying case. The action is quite complex and operates on the 'release of tension on the lever' principle to circumvent the Martin-Vibroplex patent. Pressing the left lever or pushing down on the left top cylinder pulls a diagonal metal rod away from the vibrating lever allowing it to vibrate. Releasing the lever returns the diagnonal rod to its original postion thus damping the ocsillating lever. Pressing the right knob or pushing down on the right top cylinder pushes the dash contact down to make contact. The two cylinders usually have round knobs press-fit into the holes in the top. They are missing in this key. Moving the shorting lever to the left locks the dash contact in the closed position. The key is stamped: THOS. J. DUNN & CO., New York. PAT'D 1909 and it carries serial number: 1062. Since it was common to start numbering keys at 1000, this suggests that it may actually be the 62nd Dunduplex manufactured. You can see some of these details in the following pictures:

7110 SUB-MINIATURE VERSION OF THE "ULTIMATE" POCKET PORTABLE BUG in it's ORIGINAL WOODEN CARRYING BOX:(59KB) This is an unique sub-miniature version of the "Ultimate" miniature right-angle bug. It came in its own original carrying case that also has the Ultimate label on top. The bug measures only 2.3 inches wide as compared with the 3.5 inches of the classical "Ultimate" bug. It's cover is inscribed: The Ultimate Transmitter Company, Los Angeles, California and there is a star with the number '73' in the middle between the manufacturer's name and the place of manufacture. Trade Mark Registered. Patd 6-23-25.

Trade Mark Registered. Patd 6-23-25. Number 15943.


7125 DOUBLE-LEVER 'ULTIMATE' POCKET PORTABLE BUG:(10KB) This is an unusual version of the ULTIMATE all-chromed miniature right-angle bug. Its cover label is inscribed: The Ultimate Transmitter Company, Los Angeles, California and there is a star with the number '73' in the middle between the manufacturer's name and the place of manufacture.
Pressing the left lever to the right makes automatic dots. Pressing it to the left makes manual dashes. Pressing the right lever to the left also makes manual dashes and pressing it to the right does nothing. It is unclear why the right lever was designed into this key since it does the same thing as the left lever with respect to dashes.

7130 UNUSUAL STRAIGHT 'ULTIMATE' MINIATURE POCKET PORTABLE BUG:(30KB) This is an unusual version of the ULTIMATE all-chromed miniature bug. Most Ultimate bugs are of right-angle design and have a cover. This key is simply a straight-line bug with a few unusual design features. The damper consists of two washers, the lever travel is limited by an unusual vertical shaft with an offset screw holding it up. The bug carries serial number 141 or 144. Slight damage to the plating makes the last digit uncertain. Its label is inscribed: The Ultimate Transmitter Company, Los Angeles, California., and there is a star with the number '73' in the middle between the manufacturer's name and the place of manufacture.

7160 * BUNNELL-MARTIN FLASH KEY Model 5-46:(18KB) Unusual vertical post pivot design thought by Bill Holly to be the possible precursor to the Rotoplex design. Circa 1940. (Traded to K5VT).


7166 GRAY-BASED BUNNELL FLASH KEY MODEL 5-45:(29KB) In 1939, Bunnell bought the patents for the Bunnell-Martin Flash Keys and apparently dropped the -Martin name from the labels. This is an unusual gray-based model of the Bunnell Flash Key. The label reads: BUNNELL FLASH KEY. TYPE NO. 5-45. Manufactured by J. H. Bunnell & Co., New York. Made in U.S.A. New York.

7166b A close-up of the label of the Bunnell Flash Key:(20KB)


7170 D & K DINGER RIGHT-ANGLE BUG:(24KB) This bug has an amazing action designed to circumvent Martin's patent by producing dots through 'releasing' tension on a spring rather than creating it. The release of tension allows the weight to ding back and forth on the spring and string and it makes a contact every time it moves toward the lever. The mechanism and operation of this bug is quite interesting and unique. The shorting lever is stamped: D & K Manufacturing Co. Cleveland, O, and Pat Apr 27, 06. The D & K Company was owned by Paul Dinger and August Krastin which explains the unusual name of this bug. The frame post is stamped pat appl for. It carries serial number 2482 stamped into a metal plate cast into the underside of the base. This bug is quite similar to the Mecograph right-angle bugs also made in Cleveland, Ohio.

7188a BUNNELL '' ORIGINAL BUG '' number "I": This is the 'father' of the Bunnell Gold Bug and the rarest of the Bunnell Bugs. It carries the number "I" scratched into the bottom of the brass base.
This key was designed to avoid conflict with the Martin patent that covered semi-automatic keys that TENSIONED a main spring to produce a string of dots. Several manufacturers including Mecograph and D & K designed keys that RELEASED tension on a spring to produce a string of dots. This Bunnell bug is very complex. It also RELEASES the tension on its main spring to produce dots. The main spring is held against the damper by a long tension releasing lever that dips down to pass under the dash contact, curls around under the main spring, and ends in a screw pressing on a coil spring. When the knob is pressed to the Right, the tension releasing lever moves to the left and releases the tension in the main spring allowing it to swing to the left and make a string of dots by bouncing against the dot contact on the left.
When the knob is pressed to the Left, the tension releasing lever moves to the right and pushes harder against the main spring, bending it just enough to make contact with the dash contact on the right.
The key has a rather mushy 'feel' due to the 'bending' of the main spring to make dashes and Bunnell may have abandoned this design after making this first key. However, since this key was used on a mine railroad in New Hampshire, at least this one 'Original' model Bunnell key was sold commercially. The base is stamped J. H. Bunnell & Co. New York, USA and ''patent pending''.
Bunnell appears to have used some features of this 'original' bug in his 'Gold Bug'. The 'Gold Bug' also has a mushy 'feel'. It was not very popular. The Bunnell 'Gold Bug' was made after the Martin Patent had expired so it did not need to RELEASE tension on the main spring. Historian John Casale, W2NI, discovered that the original patent for this key was issued to John Gehegan. The patent in the Gil Schlehman, K9WDY Telegraph Patent Collection may be viewed in a link below:

7850 * EXTREMELY RARE GERMAN JUNKER BUG:(25KB) This is a very hard to find bug made in Germany by JUNKER. The bug was made in very very limited quantities for use with a special radio transmitter used by the West German police. The few existing bugs were thrown into the trash. Collector Matin Odenbach, DK4XL was kind enough to provide me with this picture and to allow me to use it in my museum.


7860 EXTREMELY RARE GERMAN HANNES BAUER BUG:(15KB) This is a very hard to find bug made in Germany by Hannes Bauer. The construction is very similar to that of the Hannes Bauer paddles and uses stacked brass blocks separated by races of ball-bearings. Take a look at the paddles in the keyers and paddles section of the museum. This rare bug is the property of collector Martin Odenbach, DK4XL who has kindly provided the picture and allowed me to include it in my museum. The bug was originally obtained from a retired police officer who was involved with operating police radio stations in the most northern part of Germany in the 60's and 70's. These bugs were produced only for the german police. That's why the bug has no label or anything which could be helpful to identify it. Only a handful were made, roundabout 15, not more, in the 1950's.
When switching the German police from CW to the modern communications they stored these bugs somewhere. Within a general scrapping period they were found in the year 2001 and, as usual in Germany, they were scrapped without asking a collector ... Only two of these bugs survived this disaster. The one on the picture is in really perfect shape. It is very similar in general design to the

These include the heavy cast base and the unique red triangular paddle. Nevertheless, this key is quite different in overall design from the others. It is probably an earlier version of the keys shown above. It was made in Bamberg Germany by Hannes Bauer. It was found in Germany in 2001.

Only 10 of these bugs were made during the period 1942-1943 in the workshop in the small Swiss villiage of Schwarzenburg. This bug was purchased by a Swiss Amateur Radio Operator who did his military service on board the ship: "Chasseral". The bug was in his radio room when, on April 22, 1944, the ship was heavily damaged by aircraft. The German Navy saved the people on board and towed the ship into the nearest harbor. The owner took his key with him when he left the ship. Collector Jan Skoldin, SM5LNE was kind enough to allow me to tell the story of this key and show his photos of it.

The pendulum is drilled and tapped at the far end to accept an extension arm to slow the speed. Neal McEwen (K5RW) tells me that the key carried a CJBxxxx Navy number.- >TR

7930 UNUSUAL SPECIAL LIONEL - VIBROPLEX HYBRID J-36 BUG:(33KB) This is a very unusual J-36 bug which has a partly Lionel J-36 mechanism and a partly Vibroplex J-36 mechanism mounted on an unlabeled Vibroplex J-36 base. Instead of a Vibroplex label, the Base carries the stamped words: SIGNAL CORPS KEY J-36. The only other unusual markings are the red letters MFP stamped on the end of the key. MFP stands for ''Moisture and Fungus Proofed'' and indicates that the key had received a special coating to reduce corrosion and deterioration. The Lionel J-36 bug was a licensed copy of the Vibroplex Lightning bug which was made during WW-II by Lionel because Vibroplex could not produce them in adequate quantities to fill the needs of the military. This bug was probably one of the very early Lionel J-36 models which was produced before Lionel developed its own Label and some of its own parts. Vibroplex most likely supplied the base without the label and some parts and Lionel added the other parts of the mechanism. This key clearly never had the vibroplex label and one of the two holes designed to mount the label is still filled with the wrinkle-finish paint. At least one other similar Lionel-Vibroplex hybrid J-36 is known to exist.

7937 EXCEPTIONALLY RARE AND INTERESTING "JOHN PINELLI ""J-36"" BUG:
This is the only known example of the fascinating John Pinelli Bug. It is owned by his family and shows an exceptional degree of innovation in it's reversed vibrating lever. It was designed as a bug for the military to use in WW-II and was submitted by it's inventor for Signal Corps Approval as a J-36. I am awaiting further information about whether it was accepted or even given a trial by the military and for more information about John Pinelli's life and work as an inventor.
For now, I can only display the key and the original patent drawing as I hope to receive more information.

The label indicates that this bug was made for the RCAF and that its RCAF Reference Number is 10/7390.

7994 UNKNOWN BUG WITH VERY UNUSUAL KNOB:(28KB) This unknown bug looks very much like a Vibroplex Original from the 1920's.

The cuff of the fist carries the letters: J. H. I. You can see this symbol in the following pictures:
