I may not have been clear due to a couple of typos in my question which I have corrected herein. In any case, I know how variometers work and their history. The question was "what unit was this coil originally meant for?" ARC-???, BC-???, possibly a ham transmitter, whatever?

Can anyone help me identify what unit was this coil originally meant for? It is 2-inches in diameter by 2.25-inches long and is marked L-107. It has a coupling coil inside that can be rotated for minimum to maximum coupling via the shaft that projects out at one end at a 45-degree angle. Its rugged, quality construction suggests a military unit of some kind.
