Sorry it took a while to get back with pictures, but here they are. (Been up to my ears in washing, testing, and sleeving 78s.) Please see the first post in this thread re the issues.

Those weights look suspicious on that governor, and the felt. They look like soap! WTF

I've seen a lot of columbia governor weights with that stuff on them. I think they used lead, which can form lead carbonate (white lead) when exposed to wood vapors, especially oak.

That would explain their look! I wonder if you could weigh them and replace with a better . later weight.

Nope, not soap, some sort of felt. As for the weights, normal lead oxidation.
