I picked these yesterday. I have 9, 12, 13, 14, 15 mm. The PN system is easy: 57 followed by the size in mm.
ID these USA sockets?

So far, the best guess I can make is ProAmerica/KAL. They're the only mfr. I could find using that numbering, and I found a couple of ProAmerica branded metric sockets using the same #s.
