Simson Police Rework ?

[guy sajer]

Sorry I have no pics .

I have been offered a DWM Luger represented as a Simson Police Rework . I'm not sure if it's "right" . Possibly you can give me a few tips on what to look for ? I will try to describe it as best I can .

* DWM toggle , 1918 date with roughly stamped 1920 above it .
* Serial 9xx k
* "S" in a circle stamped LH side receiver in front of serial number .
* All parts are numbered in the military style positions .
* 4 digit number stamped rear of frame above lanyard attachment
* sear safety intact
* no police unit stamps on front strap
* right side receiver proofs same as in Costanzo "World of Lugers" p293 1918 DWM example #127
* barrel proof Costanzo page 282 #2 RH side

Other than the "circle S" , sear safety and the 4 digit number on back of frame , I see no other non-standard military markings .

I realize it's tough to tell without visual inspection , but any opinions are appreciated .

Thanks !
