Thank you very much for the offer but I think I need more info than I want to impose on you for. I have almost 100 serial numbers ranging from about 200 to 57000! The reason I'm interested is to try to establish a "no earlier than" date for the police unit marks on these pistols. To simplify things, I'm assigning a 1920 date to any pistol manufactured in 1920 or earlier since, for dating Weimar police marks, this represents a "born again" date. The highest s/n in this group having a 1920 Reichswehr property stamp is about 25000 so at least about 80 pistols may be labeled as "1920" for my puposes. This leaves about 20 pistols ranging from 278403 to 571979 that I would like to establish dates for, unless they were all produced prior to 1921.
I guess my basic question is "What serial number represents the start of post-1920 production?"
