Am now looking at the shadow meter. This set has one of the "older" versions. See Chuck's pages on servicing these things.
A look at mine and you can quickly see that the pilot lamp for the shadow meter is missing.

The insides were relatively clean although the vane has some crystallization of some sort on it.

I started to try to take it off with a Q-tip and alcohol but quickly decided to leave well enough alone. I was getting cotton fibers onto it and since the vane repositioned to center very nicely I know the magnet is good. The coil ohmed out a about 500 ohms and a 9 volt battery across the coil deflected the vane all the way so that is working as well.
I'm will see if I can locate another pilot lamp mounting but if that does not work out, I do have a modern bayonet mount that I can probably MacGyver into place.
