Still trying to finish my Tuska restoration and I need the parts shown in the links below. They are the filament rheostat and knob with a pointer. If Worse comes to worse I would settle for just the knob. Anybody have something like this in their junkbox to sell or trade?

Try Mouser electronics for rheostats, as for the knobs, someone else here might have a reference.

Try a search for the rheostat
