Luger and his brother from another mother.....

At sn 253xx your pistol is also very early Manurhin production, probably from 1954. I've been interested in understanding the point at which the logo banner on these pistols changed to the later one. Your pistol is from the first marking variation.

The PPK was a compact version of the PP.

The "K" follows the German word for "Detective": Kriminalpolizei by branding it the "PolizeiPistole Kriminalmodell".

It was the smaller pistol they preferred carrying in plain clothes.

Your Manurhin PP is in .32acp, of course
The "K" in "Kurz" is for "Short" in German, and is how they describe a .380acp cartridge there. "9mm Kurz". In a similar vein, the Spanish call it the "9mm Corto". It is, of course, possible that the more compact pistol also had the unofficial nickname "short" in German.

PPK advertising clearly referred to it as the"Kriminalmodell".
