    But I have seen 40-60 - I think it was used in the auto body business, before lead was outlawed.

    Possibly it's different in US, but here in Germany it's Pb60Sn40.

    Any solder I've seen is labeled with the tin content first, even lead-free solders have the tin content listed as the first number. I have two old 'rolls' of acid core solder in my tool box labeled as 40/60 (40% tin / 60% lead) and 30/70 (30% tin / 70% lead).

    The Kester company lists tin/lead 'bar' solder in several alloys, 63/37, 60/40, 55/45, 50/50, 45/55, 40/60, 35/65, 30/70, 25/75, 20/80 and 10/90.

    So if your bar solder is labeled or stamped 40/60 it's probably 40% tin.

    NOPE, cast onto the bars are "National Lead Company" and it's 40/60

    I also have some extruded Kester bars which are stamped Sn63Pb37
