Raimey,
Thanks for the article about August Heym. By the time I got there, he had died and somehow Mauser had taken control of the company and were making Mauser Mod.2000, 3000, 4000 rifles and sub caliber(14.4mm) training devices for training of 105mm Artillery forward observers, and some automobile parts as well as Heym guns. When I went back for my second tour, the courts had returned ownership to the family and August's widow was the owner. As far as I know, she and August had no children.
