I've acquired a 6# case shot that was recovered from the Alabama river at Selma in 1974. As you can see from the pics, it does have some loss on the outside from its time under water. The outside is also coated and has a distinct mold seam. My question is about the inside. It is untreated and contains 10-12 case shot still in the original matrix (with the exception of two case shot that are loose). Should I leave the inside alone or what do you suggest? Wax? Gemplers? Something else? Also, what would the approximate value be? I would also like to acquire an appropriate Bormann fuse if someone has one for a good price.
