I have a question about differences in coloring. Last weekend I found a 32cal PPK with box, rod, and manual at a pawn shop that had the opposite coloring from yours. Grips were brown and mag extension was black. Marking on barrel says 1966 manufacture and there was no country marking - no West Germany, no Germany. Price seems reasonable but I'm not personally a fan of 32 cal. Is it worth picking up. Price was $550.
Weird about the grips. My '68 ppk in.32 has brown mag and grips. Maybe the pictured grips are off a later gun as they are marked interarms. I would say mismatched colors are the result of their not being original.
