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.

See the pic at http://www.fidnet.com/~seanbart/SCR-...-443-A_Top.jpg , I
think the rod is there to act as a stop, there is a pin on the sliding
piece that hits another pin at each end of the lead screw and inhibits
rotation.
