Got some babbit ingots too, grading/content papers are with them.
oh wait I have 2 mystery ingots, I was melting lead pipe I had been collecting and was getting near the end. Added something that was not lead, pot started to solidify, turned up the heat and scraped all of it into the ingot molds. The stuff is heavy like lead and hard like a brass or harder. 1st pic, 2nd is old pic of aluminum ingots last count we were up over 700 pounds, lead was in the same range, but made lead hammers 6# and 3#.
