[Milsurplus] J-37 key, need button

[Hubert Miller]

For a common U.S. military radio telegraph key type J-37 , I need the plastic button only.
I know this is a long shot, but I had to try. The key has a button 1.5 inches in diameter, black
plastic, with a fastener that looks like one of the knurled screws from an old No.6 dry cell
1.5 battery. That doesn't look original, yet it fits perfectly, and the plastic button does not
look like it was repurposed from some other gizmo. Or is this the way the key was actually
made? I noticed the key arm has a black plastic cover on the last 1.5 inches to the button
center, like maybe the key had high voltage on it and was in a cover of some sort? But the
thumbscrew holding the button is not insulated, so something's not right here.
Your idea?
tnx
Hue Miller
