DWM 1914 Artillery Luger 9mm caliber pistol. 1915 date. Fine tune front and rear sights. Bore is good with rifling showing wear. Upper parts of the gun such as barrel, barrel extension, and toggle match. Frame and lower parts match each other but do not match the upper parts. Action works perfectly. This is possibly a campfire mismatch, such as soldiers disassembling guns to clean, and paying no attention to reassemble, you get a mismatch. Priced very reasonable for an artillery Luger.
