Hi Breck –

Yes, it is a US key that was used on a WE test set. There may even be a number on the knob as there were 4 keys on the test set. Of course most of them were removed by hams. I believe I still have one complete test set downstairs. BTW, the original purpose had nothing to do with morse code. They are neat little keys. 73 – Mike

Was going through my keys and found this. Anyone recognize this key. Is it military ? Does it mount on a small transmitter or miniature telegraph console?  Very well made. Several adjustment screws and has a "shorting" switch and  two long mounting bolts.
