Default Re: Weird 'thing'...

If you slide the chrome 1-20 scale across, it moves the wiper on the long wire wound rheostat behind the front panel. The contacts closing after a cam/gear has rotated seems to send to/ come from the adjustable tapping pints on the sarong wire wound at the rear.
It's very old- the woodwork is lovely, has the strange amber glass front, and inside the rear wooden panel was a sheet of white asbestos!!!

On the left is a round female multipoint labelled 1-11- different dc outs to something? Or from something?

It's the numbering right to left and the handle for rotating the shaft being on the left also
that's gets me....
