I picked this one from a good friend of mine yesterday, and I have noticed some rather interesting things about it. First is the pitting on the right side of the slide. I asked him about it, and he told me that his father (who brought it back) had always said it was blood. He had told them that it came off a dead German in France. I have no reason to believe that he would make this up, but I never really thought of blood pitting metal. It makes sense though! Another very interesting thing I noticed about this pistol is that it bears BOTH WaA613 and WaA103 Waffenamts. It falls outside the serial number range of WaA610 by about 4500. The barrel and slide have both, while the frame only has WaA103. Has anyone seen another with these markings? My guess is that it is a transitional piece between WaA's. Opinions? Also, does anyone have an extra 1922 Luftwaffe holster they wouldn't mind getting rid of?
