I will have to bow to Thor's references.
The serial number of this gun WAS 2432...before I obscured the markings on the photo.
As I stated above, the photo we use for the front page has been altered so that no identifying marks are visible... makes for a nicely finished generic sample of Georg Luger's Masterpiece...
When I captured this photo, it was identified as a 1937 Kreighoff... but Thor's authoritative sources say 1936.
That was fun. We will have to do this again...
