The closest one in the Red Booklet to mine is 233488/K. This K below PPK I have is serial number 233271/K. The booklet by Marschall and Gortz also is known as the RED BOOKLET. This K below serial number PPK has become known and associated with the SS as a result of research by Dieter Marschall and Joachim Gortz and their booklet entitled SS Walther PP/PPK 1939-1944 and further research by John Pearson and his series of articles expanding on this work and published in Auto Mag (NAPCA) in four (4) installments. This one is special not only because of the high grade condition but because it has two (2) K below matching magazines and a near new vintage/period black DRGM (akah) black side mounted magazine pouch and ink stamped inside the flap Walther PPK holster. Well, I am pleased to present here a just acquired very high grade and pristine condition what I call a Third (3rd) variation SS PPK.
