Can somebody tell me if these markings are "OK" on a 1916 DWM?
First is this serial number stamp on the extractor:

Is being "offset" like that acceptable, or is this an example of "Forced Matching"? Font looks the same as the rest of the pistol.
Secondly, I haven't seen this proof in this location on a DWM before, but I admit I am a noob, and don't have any Imperial Luger books...Yet:
Thank you very much for your enlightened education.
Happy Holidays!
