I have been sporterizing Mausers for 49 years.
The Kuehnhausen books on Colt double action revolvers are so good and the his book on Mausers is so bad, I can only speculate what happened.
This is speculation..
The Colt factory spoon fed him with in house manuals that were very good. Then they proof read his books for him.
The Mauser book was just some lecture notes from teaching a class, without the drawings that would have been on the black board. No editor alive would have allowed that mess to be published because of the scatter brain organization. It went to publication without being read. The verbal part of the lectures about money were left out. Like, "We all know that the interior structure of a Mauser is soft, but if you really want to screw over a client and take him for all he is worth, tell him you are sending out his Mauser for heat treat. [class laughing]"
Then something happened. It was like the Roswell incident. The gov said the balloon was a flying saucer, and that information fell on fertile ground. Many WANTED to believe that.
Likewise Kuehnhausen has spawned a generation of Mauser heat treat believers that true Mauser bolt faces while wearing tin foil hats.
