Spartan Solder

[bushwack]

I have 1lb of spartan solder. It said solid wire on the box but it does not give the tin content. Does anyone know how much tin this would have in it? It has to be old because the box does not have a bar code on.
Thanks for your help, bushwack

jf it that old,it is probley 50/50 solder,is the solder kind of a dull gray? the lead will oxdise in old 50/50. it will be 50% lead,50% tin.if it is shiney,it will be 95/5 95% tin,don't remember the 5%. in the old days us plumbers only used 50/50 or 95/5.
