Rear Connecting Pin

[bill m]

A 1916/1920 double date was originally a 1916 DWM. You did not mention if it was a police gun or not, but I'll presume that it is, (has a sear safety). Anyway, it was not originally issued with a numbered pin. The 1920 date is actually a property stamp showing this gun was the property of the Weimar military or police. The rear pin was not numbered at this time. The rear pin being numbered indicates that your gun was reworked in 1932 or after. That is all it indicates, that it was reworked for the Nazi military or police in 1932 or after. Most of these reworks were for the police and were fitted with a sear safety and a magazine safety. Once in a great while you find a Weimar gun without a numbered pin.
