Re: The wrench stamped D.G.R.M

DRGM stands for Deutsches Reichsgebrauchsmuster (German: German Reich Registered

It essentially means what we in the USA refer to as a "Design Patent" of
national scope.  (As opposed to a provincial design patent.) The term was
replaced with Deutsches Bundesgebrauchsmuster' (D.B.G.M.) in 1952.

I learn something new from the Porch almost every day!
