I was recently gifted about 200lbs of lead weights that were said to be 'stock car' weights.and like from the 60's..
They look home cast in like a loaf cake pan with bolt holes drilled through them.
I brought a couple down to the recycle/scrap yard and had them tested with their gun and was kind of surprised...as I thought they would be made from wheel weights, but they seem too pure.. Results all averaged about the same at 97.6% Pb & 1.38% Sn
Were older wheel weights a different composition then newer ones,, or does anyone have any idea what this lead might have been salvaged from ?
Not that it really matters much,, I'm over joyed their so nice,, I'm just really curious...
