luger id???

[DAVID]

This is a strange one to me. If anyone has any ideas on the correct id on this I would appreciate.


Pistol was purchased as a 1920 .30 cal.

barrel is unnumbered but stamped Germany on side.

Frame is numbered xx55 r. and stamped Germany on left side.


Breach block is unnumbered with horizontal Crown N proof on left side. Does have two numbers at the very rear of the opening for the firing pin.


Rear toggle is numbered 55 at rear.


Front toggle is unnumbered and Marked DWM. has some inspection numbers underneath.


Receiver is unnumbered but proofed with Crown N on left side.


Wood grips are numbered 55 inside.


Side plate is numbered 55 but in the commercial hidden location.


Take down lever is numbered 55 and also in the commercial location.


Rear toggle pin is numbered but mismatched.


Any ideas if this is a correct ?? 1920, 1923 or ??
