They're similar, but not the same key.

Jim-

These keys were provided by several different makers. If you find a
J-37 and a J-38 made by same company, there is a chance they are
identical except the switch-related hardware is missing from the J-37.

That may not be true for all makers, but it was in one case I'm familiar
with. It appeared that the switch hardware could be transferred from
the J-38 to the J-37 without any modifications.

My memory from the 1950s is a little dim. I can't find my original
J-38, but did find several other keys I've picked up over the years.

There is one J-38 like my original one from the 50s. There are two J-37
keys: one like you described and one like the J-38. One of the J-37s
is mounted on a knee-clamp!

The J-37 that is like the J-38, has the switch part attached to the hot
contact. However the place where the switch lever would bolt to the
base, is missing. I think this was the case I remembered from years
ago. Half of the switch is there, but there is no provision to attach
the lever.

NB-

As you asked in your original post, you need to find a key. Any key.
And get on the air! Your code speed will improve more rapidly when you
are forced to copy in a way you can't when listening to a recording.

It may not matter which style of key you get, as far as RSI is
concerned. You can operate either kind without resting your hand on the
desk.

One feature you may like is a Navy knob. The Navy knob has a round disk
under the knob. You can make one by drilling a hole in a poker chip,
and mounting it under the original knob.
