I couldn't find any articles in the 1950s index editions. The 1948 and 1949 versions were indexed differently, but there wasn't anything in those, either. Several on the K38 and Combat Masterpiece, the 38 versions of the guns you ask about. That pretty much eliminates those years as sources for reading.
The next best option would be to try to find the books by Skeeter Skelton. He was a big advocate of the K22s, and his writings were a big influence on me (my downfall, according to my family.)
