Ive found a bar of metal that is enscrypted Bunker-Hill Super-Nickel Babbitt.?
Does anyone know about this sort of thing?
Answer:
Super nickle babbitt is about 92% tin, 6 % antimony, and 2% copper and other trace metals. Bunker-Hill is the name of the foundry that was in Wallace, Idaho (?) but went out of business in the early 80's.
