Had this piece for many years, I think it was in a POWR-KRAFT 1/4 inch socket set I bought used in the 1960's. I knew at that time it wasn't P-K but had been added by some previous owner of the set. It has JSB in a circle on one side of the handle and SS10 on the other with no other marking anywhere. Has anyone on here heard of JSB? I searched AA, ebay and the internet and came up zip. TIA for any information you may have.
