It's tin plated, DIY. Not very original but I was playing with it. There was some rust so some of the original plating was gone. I didn't want it to rust again so I tin plated it. Tin is much brighter than what was used originally. the tin will oxidize over time (just look at the typical tube shield). Unfortunately, it is very difficult to do the chassis. The aluminum shields are spun on and all of the sockets would have to come off. It cleaned up pretty good but definitely is a different color than the tuning cap. The rust that was on the chassis was very light and came off without rust pitting. Not sure if these things are cadmium plated or zinc plated. I'll need to put some sort of film on it to keep it from rusting again. I suspect that zinc plating on the cap would have looked much more like the chassis but I don't have zinc plating capability yet.
Nathan, I didn't realize RD had that! Thanks, but I was able to salvage the original. Not perfect but at least original, not that the radio is going to look exactly original, but...
All of the resistors underneath (except WW) are between 50 and 300% over value so I may try making some. There are only 5 and they are all the same physical size so shouldn't be too bad. they are the type with the molded lead ends so a bit more difficult than the type with the wire wrapped around the end. I probably could get by with hiding a parallel resistor underneath.
