Vibroplex J-36 Ser#159 - N8UX The J-36 Bug Census Project
Update: April 15, 2013 - Fixed a few broken links to qrz.com.

Update: Dec 28, 2012 - Best wishes for a Happy New Year in 2013! I continue to receive your pictures and J-36 info. Thanks to all who have contributed, and continue to contribute to this project. I hope to add more historical information on the J-36, and I've written to ask permission from authors to reprint it here. I would also like to include a photo gallery of all your great J-36 pictures, and hope to get that done here in the coming months. Yes, this web page is SO 1998... and I'm behind on the census table. But rest assured that the data is saved, and as time permits, I'll re-code the page to look more like something out of the 21st centruy -HI. Thanks again, 73 es zut, pass the word, and stay tuned... Rich, N8UX

This page has been created to gather information on existing Signal Corp J-36 bug type telegraph keys, in order to calculate estimated production numbers of the various manufacturers and orders.

If you have a J-36, be it manufactured by Vibroplex, Bunnell, Lionel, or Brooklyn Metal Stamping Co. (scarce), or know of anyone in your radio club or community that may have one, I want to hear from you!

What Information Do I Need?

The information required is located on most of the nameplates. This consists of:

  • Manufacturer - Vibroplex, Bunnell, Lionel, or Brooklyn Metal Stamping (BMS).
  • Order No. - Will look something like this - 21984-Phila-42.
  • Date - Something like 6-27-42.
  • Serial No.
  • And any other distinguishing or unusual markings.
  • Optional, but highly desired - A .JPG photo of the nameplate and/or entire bug.
  • It is assumed that Lionel J-36 bugs have an order number of 7861-Phila-43 and a date of 1942, but please double check to make sure your Lionel has this order number.
    It is also assumed that Bunnells have the order number of 6001-Phila-43 and a date of 8-4-42, but again, please verify this on your Bunnells.

    Your particular bug may not have all of this information on it. Most Lionels no longer have their original nameplates, or reproductions have been applied in their place. If so, please state that it is indeed a repro plate. There are some Vibroplex transitional variants that have no stamped numbers - please let me know if that is the case. The author is aware of the various order numbers, and dates that correspond to them. But please include all the information so as to maintain the accuracy of this census. Basically, the more descriptive you are, the better.
    Put all of this information in an email, along with .JPG photos, if possible, and send to this email address:

    I will then place all data in a master database. I'll periodically post the breakdown of manufacturers, order numbers, and highest serial numbers found here at this web site.

    My thanks go out to Paul Bock, K4MSG, for his excellent research and article in the July 1998 issue of the Vail Correspondent, as well as Yann, F5LAW, Mitch, W4OA, Lynn, N7CFO, Tony, WA4JQS, the Morsecode and CW mailing lists, and all of those who have so far contributed data to this project.
