WW2 rework?

A couple years ago I purchased a DWM 1918 Luger. Serial is 50xxm and all numbers match except for the safety lever. This pistol came with two matching fxo mags (with aluminum base) suggesting it saw service during WW2. This P-08 was also refinished after WW2. It exhibits the West Germany federal eagle proof mark (the one used between during 1950 and 1971) in addition to its original WW1 Imperial and Army proof marks (one of each only on the right side of barrel extension). There is even a St.Andrew's cross on the barrel indicating that at some time of its history the pistol was deemed unfit for service.


Most probably this pistol was reworked during WW2. What really puzzles me is that it shows none of the military proof mark or Waffenamt acceptance mark used during that era (except the eagle/37 on both mags). It is hard to believe that the meticulous Germans performed the repairs and returned to service this handgun (and thousands of others no doubt) without proofing it. Why then didn't they apply the proof and acceptance marks accordingly? To save time? Once the job is done, stamping the gun is an easy, short step. Besides, all P-38s, Walther PPs and PPKs were proofed until the very last days of the Third Reich in April 1945 when the Germans were hard pressed more than ever.


Is it possible that the rework occured in an Army equipment depot where there was no Waffenamt staff? But then the pistol should show the KU marking anyway?


Does anybody have more information about this specific variation and more specificaly why some of these WW2 reworks don't exhibit the usual proof and acceptance marks?


Thank you for any input.
