Probably from a SCR-269 (BC-433) or ARN-7 Radio Compass. Loop, 2 RF,
Oscillator and Mixer tuning.

The capacitor has a second gear driving a sliding rod, probably used to
move a dial pointer (see the two gears below the worm gear?). I suspect
the radio was tuned via a motor connected via a spline to the worm drive
and the moving rod was somehow connected to the dial pointer.
