I picked up a tap wrench at a estate sale today. It looks like a GREENFIELD. It is marked,
OK.
MADE IN USA.
NO. 15
012
It was painted red at one time, with very little paint left. It opens up to 5/16. All steel with knurled handles. 11 inches OAL with the jaws closed. Seems well made with close fitting parts. I have never heard of a tool brand called OK. Any info would be helpful. Thanks,
