The other day my dad picked me up a set of proto professional sae wrenches at a garage sale for 15$! 1/2 is missing, and the guy replaced it with a snap on with owner marks. Would love to find the 1216 that fits the set. On one side it says proto mfd. USA, the other side just says professional S, with the S being sideways. Found a couple on eBay, but could anyone tell me what that S means? Any idea of dates?
I'd believe the pouch they came in was from 1984-1985.
