Another 1914 Commercial/Army
 

While on commercial 1914's, where was this used? Serial #72353, 1920 Permissive stamp on chamber, commercial and military serial number placement, Circle S on left receiver, no proofs on right receiver, #2132 crossed out on rear near lanyard loop. firing pin matches and has E/6 proof. All matching except mag and take down latch.

I think it is an early war officer private purchase that was probably brought back by an enlisted man and turned in with the 1920 amnesty. The circle S and renumbered side plate along with E/6 would indicate late Weimar Suhl rework for military use or reissue. The number on the back of the frame is typical of a pre 1922 Reichswehr provisional marking.

Is the axel pin numbered?
