Erfurt Quiz Anyone?
 

Anyone here had any ideas on the Erfurt shown below. There is no date over the chamber. This pistol has matching numbers as shown. There appears to be a date stamped on the rear of the receiver.

This Erfurt has a military history, but was rebuilt/reworked by the firm of Frankenschloss, in Suhl, Germany. The number on the back is probably the unit/armsroom pistol number for the unit whose stamp is on the front strap. It is likely that this pistol was rebuilt for civilian sale since the caliber is 7.65mm. Erfurt was a military arsenal that produced 9mm guns.

This is my best estimate based on what I see in your photos... perhaps one of the other guys may have more insight into the markings on your unusual Luger.

Welcome to the Lugerforum.

The proofs are commercial nazi-proofs that were in use between 1939 and 1945. So it was reproofed in that era.
