Sparton Junior restoration

I like what you're doing with this set, preserving as much as possible the original finish.

A lot of early sets had a power toggle switch on the side so this one doesn't really look out of place. That switch has a long threaded shank which is used for just such a purpose, going through thick wood. Why would they use such a long shank if it were to be mounted on the volume control? Is there evidence that a switch ever was originally mounted there? Or did someone substitute the long shank switch? The wiring might give a clue. That being said, you could try a modern short shank toggle on the pot; should have less force required. Maybe a ready-made wooden button plug properly finished wouldn't look too awful stuck in the switch hole?

BTW, that pot was designed by an engineer the week that the bean counters were on vacation. Built to last!
