Single End Flare Nut

Early Catalog Drawing vs 938 with a 1931 date stamp and a 9-2 (maybe a 942 variant)

Single end Flare Nut

These are the earliest I know of. They were an improvement over the normal open end wrench, because they damaged the nut less and had a better grip. The photo is date stamped 1931 (out of the range of the catalog listing)
