So my 112 has a type of volume control I have never seen before. Sort of a spring-loaded brass wheel running around inside a resistive metal band. I'm guessing that after 77 years it could do with a cleaning (though i have not heard audio through it yet...so maybe it is fine? it appears scratchy when i monitor its resistance with my multimeter).

So is there a good way to clean these? Should I just leave it alone?

Here is a picture of the workings:
