"It can't be both Swiss and DWM; pics! "
FWIW: I own a Luger that was given to me (free) (shortly after the owners death). I initally thought I had really scored. However, after getting home and examining it in more detail, I realized that it was a parts gun. The frame is Mauser, the toggle is an American Eagle (I think that is the right term), and it has a six inch navy barrel complete with two rear sights.
The real sad part of the story is yet to come. When this was given to me, I had my choice of one of two Lugers. One was a pristine WWII bringback (captured and brought back by the recently deceased, and it was the first centerfire handgun I had ever fired, when I was a kid) complete with the holster and all the accessories. It was made in 1936 and was in VERY nice condition. However, I already owned a couple standard 4" barreled Lugers although neither was anywhere near the condition of this one. So, it was a tough choice. I chose the one I did because I thought I was getting an Artillery Model. The good one was given to someone else.
