These pair were up for destruction in Kosovo a few years ago. They are now safe in the Celle Garrison museum.
The markings on the MP 40 can be seen in the photos.
The Luger is DWM 1917 with a unit stamp in front of the grip (2nd photo).
Sadly both had to be chopped in order to be brought back as trophy weapons, the paperwork was horrendus and drained hours of my life but worth it in the end
