Has nothing to do with Turkey Day, actually. Anyone older than thirty is prohibited from answering until the correct answer has been submitted.

(Probably) un-helpful hint: There's at least one good picture here on CB that shows the item in context.
 
Or a table saw handle for the angle.
 
Probably for adjusting the carbon rods on something, but I don't know what.

How many things in the theatrical realm can you think of that use carbon rods?

By not answering us does that mean that we are still wrong?
 
Ah yes, the crank handle off a Strong Trouper! (Not Super Trouper) AC Carbon Arc spot which was the baby sibling of the Super. Unfortunately, I have seriously violated the age rule! :(
 
Of course its off a Trouper.

Bonus point (easy one) if someone (other than Derek and also under 30) describes what the little adjustment ring on the shaft of the crank did -
 
As I remember, the crank moved the carbons toward or away from each other (changed arc length) and the knob was to place the arc at the focus of the reflector, i.e., move the entire arc toward or away from the reflector. Btw, the two knobs tilted the reflector on its horizontal and vertical axes to put the other focus of the reflector on the axis of the instrument.
 
Bingo to SteveB and JonCarter! It set the arc focus/depth in the reflector!
The feed on the regular trouper was also automatic (Clock type motor) but the trouper did not have the "pull-to-strike" on the positive carbon holder, so you had to crank them in to strike and then back them off to set gap.

Ah yes! The wonderful days when running spot felt more like you were operating a locomotive!
 
After the knobs on the H&C 150 amp arcs we thought we'd died & gone to heaven when we got the Troupers.

Off of one of our 2. We still use them.
