For Sale: Tested and working great vintage 1950's US Army code trainer with one J-37 morse code key.
Fully tested and working- hooked up the key and found the audio beep response to be good and the light is also working. You can adjust the frequency/tone of the audio. All the switches and controls are working correctly. This model can store a bunch of these keys in the lid and they can all be wired together so a whole bunch of people can practice code at the same time. This came with two keys when I found it, the other key is being offered in a separate listing. Made by the McElroy Mfg. Corp.
Shows some cosmetic wear and can use some cleanup. The heavy duty wood case is in pretty nice shape. There are no apparent broken or missing parts.
Here is YouTube video showing the coder in coding actions:
