There is one speeder I found used. 1/2 drive, chrome, on the drive end instead of a fixed male square 1/2, is a roll-head 1/2 flex head aka breaker bar. Could be used to break loose fasteners, then flip to straight to unscrew, save switching to a different handle. Name on it is OTC, Owatonna Tool co. Which is partially ground off, factory use? Factory made for sure. Maybe arrived when air tools were becoming the norm. Have 1/4 in, 3/8, and 1/2 in. but the one most used is a 3/8 Craftsman, handle has a ball bearing, plus the C in the name wraps clear under the M, which indicates 1940s manufacturing?
