Hans Tauscher was A major German Arms dealer in down town NYC and a suspected spy. It reads like a novel. Make sure you check out the slide show icon includeing with original luger ads! Its the only site that I'm aware to be interactive. This site is probobly the most historically important that I have come across. It traces early model like the Test lugers, 1902 Fat Barrel and Cartridge Counter~Its traces lugers that were delivered first in downtown New York City from Germany.
