I have had these for a while now. They came to me from a yard sale, along with a great little pot that holds about 25 lbs of lead. Because they came with the pot I have wondered if they're related to casting. There is a small hammer made of a soft metal, seems about like hard lead. It has a brass handle. There are the two rings you see that appear to be brass. And three little ingots of something, I have refrained from melting them, have had a lot of other projects. Does anyone recognize these?
Here's a closeup of the hammer^^
