Grantman,
Just to make life interesting, there are even lugers with a 1920 production date and the "1920" property stamp of the Weimar Republic; further even a few 1921 dated pistols with the "1920" stamp!

A little more on the "1920" property stamp, there were already many military arms in civilian hands and a bounty was being paid for their surrender under the 1920 law "to Disarm the Public".

The "1920" property stamp did show government ownership when applied; it also prevented pistols coming in the front door and out the back to be surrendered again for more $$.

In addition all small arms in the Reichswehr inventory were to be marked with the "1920" PS; so one can find "1920" on pistols other than lugers, rifles, bayonets, and even on the board stocks used with lugers.
