Several years ago a guy gave me seven rolls of wire solder, as follows:

3 rolls Woody Butts
Safeguard 50
.125 Lead Free Wire Solder

3 rolls Federated-Fry
40/60 .148
Solid Solder Wire

The other was labeled 95/5SB, which I have found in the lead alloy calculator.

The only ones I find in the calculator as 50 or 40/60 show lead as the 50 or 60, while the 50 rolls I have are labeled as lead free. The 40/60 I have is not labeled as lead free, so I presume they would be 60% lead?

Appreciate any help.

tin is the first number shown.
