Rheostat help

I`m trying to find a couple of specific rheos for a WWII panel I am restoring. I have the numbers provided in the parts manual, but i`m coming up with zip and i`m hoping somebody maybe knows a few other numbers. I`m looking for:

Switch Assembly; P.R. Mallory and Co.; part 3215J - believe it is a 5 position switch
Rheostat; Ohmite Mfr. Co.; part 5543 - it`s a panel dimming switch, it has no set positions

I`m a rookie at this so any help is much appreciated. Thanks,

If you can send me a photo or reference for the Ohmite resistor, I might be able to help. I've got some older ones around the shop. Most of the panel dimming resistors shared the same housing, etc. The primary difference was the internals, ie the resistance of the windings. So if you're not *too* concerned with absolute accuracy, I might be able to help.
