Rick,
I have 13 zinc and 18 lead balls in my personal collection. I'd take $20 apiece for them. You would not have to buy them all. I measured them at 2.90" diameter. If I recall, the zinc balls weigh in at 3.1 lbs. and the lead at 4.8 lbs. I cast them many years ago with a steel mould I have using my crawfish burner.
I also have 30 aluminum balls. They measure about 2.83". I think they are 1.1 lbs. I had my mould enlarged after casting these because I thought that was too much windage. These were done at a foundry I has access to.
