The standard WWII USAAF Morse key was the J-37.  It was used everywhere
that the SCR-287-A or the AN/ARC-8 liason sets were installed, and that
was almost everywhere the USAAF operated a multi-engine aircraft.

The J-37 is not flame proof.

The J-38 is the key that was used in Morse training setups, not in
actual communications service that I've ever found.

The NT-26003 key is my favorite military key.
