L.S.BRACH MILITARY KEY:
The J-5, J-6, and J-7 were used with the BC15 airborne spark transmitter and BC89 receiver of WWI vintage.








Incorrectly advertised and sold widely as a J-3, this key has a straight, heavy 1/2 X 3/8 X 5-1/4" brass lever with typically British design pull-down spring at far end of pivot.
The base is 1/2" thick, 4" long, and 1-3/4" wide and tapers down to 5/8" wide from pivot toward knob. The wires are sealed inside the base.








The lever is stamped:
