Just FWIW, Dr. Ingr. August Weiss was the lead production engineer for DWM/Mauser for the Luger pistol. Probably no one, except maybe Georg Luger, knew more than he about how the guns were made and how they worked. Dr. Weiss authenticated the .380 ACP caliber "Baby Luger" that Datig turned up, removing all doubt as to its originality.
