[CW] Correct key for B-17 WWII bomber?

[D.J.J. Ring, Jr.]

Understood - and I wish historians were aware of this more often -
that the "not standard" could become "usual" by use.

One key that was so, was the  Navy Flame Proof key - used as a lamp
signaling key, it was so comfortable to use, it was often appropriated
to be used by the  radiomen.  No wonder, it's a great key - much
better in my opinion than a J038 or J-37 or most.  I like it best of
the wartime keys in fact.

Thanks again,
