Vintage 4766 Proto / Urrea 1/4” Drive Breaker Bar Knurled Handle Mexico – READ!

Specifications

Same part # 4766 as a Proto USA made 1/4” Breaker Bar. Virtually identical in appearance, lacking the hole in the handle, and obviously the stamping. See pictures for the stamping, shows 4766 then a brand name with a registered ®️ symbol and Mexico. UPDATE: After a little more research, it appears the brand name is URREA. The brand originated from PROTO trying to expand into Mexico and creating the brand name PROTOMEX. The parent company split and the URREA family bought/acquired the company and changed it to URREA. (Or PROTO partnered with URREA and then later split?) The older (vintage) tools still used the PROTO designs.
