Just to clarify the Georg Luger Masterpiece identity...
I hate to burst anyone's bubble, but that graphic is a heavily sanitized version of a good photo that I collected some time ago. All visible marks were carefully obscured by digital photographic magic so that it could serve as a generic representative of the Luger Pistol.
If anyone cares to hazard a guess as to date of manufacture and who manufactured it... it might make a good guessing game.
I will post the correct answer after someone correctly guesses its true identity...
