KI 1933 Luger

Yes, it has been going around in NAPCA for over 25 years. Examining the marking closely, one can see the letters are "Kl." not "KI.". Mark Wieringa in discussion about Reichsheer/Heer reworks on the BCN has posited a strong case for reworking at the Kassel arsenal. "Kl." is the official Heer abbreviation for Kassel. The marking is similar to the Zn. marking found for Zeithain reworks. The concentration camp connection cannot be supported in source material: the abbreviations were variations of KL or KZ. And, there was no Kadetten Institute, a fact which seems to have escaped Kenyon. The only problem, is that the explanation lacks the pizazz of the other two. It doesn't sell as well.
