I realize the shape and weight will not tell me anything about the consistancy of the lead. I was just wondering if anyone had seen this size and shape before in any particular industry. For example, I have in the past bought in sailing boat lead ballast from different sources and all were the same shape and weight (26 pounds) so I thought these ingots may be familiar to someone. I have enough to last me a lifetime so I suppose if I test a dozen or so at random for hardness they should all be similiar in composition.
