Looking for info on this wrench. Stamped Witherby 2770-0 , and in raised letters Drop Forged Germany. I don't think it is affiliated with the T. H. Witherby Edge Tools Co.

All I know about it is that I have one too. Different part number though.

Hello, Don. Thanks for the reply! The one that you have is in much better shape than mine. I am still trying to find more info!!

Hello, d42jeep. Looks like the DGBM on the wrench that I have translates to this; DBGM stands for Deutsches Bundes Gebrauchsmuster (German: German Federal Utility Model) . Still nothing on Witherby.

d42jeep:
I’m not finding much.
