Getting the lead out

[user 23626]

I've posted this material on another topic, even sold some there, but now putting it where it belongs. This is reclaimed Bell System seam solder. Upon research I find it's 38/72 composition and 13 BHN. That's according to people that use it on other websites, Cast Boolits etc. I can get 18# +/- in a 7.90 small flat rate box so $20.00 if you want to try some. The virgin bars I'm saving as I see they sell for phone co memorabilia on ebay. All of this is in ingots of various sizes. Thanx for your time in looking and responding.
