Yeah, the problem I've had with the pot's is that they are pretty much encased. I know I can use that stuff called De-Oxit but even if I had some, I don't know where or how to spray it to get in inside of there. There's a picture of my pots in this thread on the previous page.
My Admiral is a 4215-C7 from around 1942, least that's what he schematic says.
