Three things:
1) It would help if you posted pictures of all the stamps and numbers on it, and posted pictures of the front, back and top of the pistol, rather than just the sides.
2) The finish looks flat for a DWM Luger and there is no wear in the areas you expect to see wear.
3) Posting the caliber would be helpful as they came in both 9mm Luger and 7.65mm Luger.
