Of course it covers the PPK/S within the PPK chart, but as Mike wrote: Chambered in 7,65mm.
Yes, I know that is what Dieter seems to have written, but I am not sure that that is completely correct. In any event the way it is written is misleading. Which is why I took care to emphasize the limitations of those two charts --that they apply to Models PP and PPK only, and only to those guns in 7.65mm.
Considering that PPK 7.65mm production had advanced to 270,000 by 1972, how does one explain a PPK/S .380 with s/n 173,174 S dated 1973? Or a PPK .380 with s/n 122,154 A dated 1967?
It would be a mistake, I believe, to draw too many extended conclusions from these or other charts that appear in Marshall's or Kersten's books.
