I started collecting .22 military training rifles a few years ago. I Started out with a 1922 Springfield. From there I picked up a few Lee Enfields, A BSA Martini action, Winchester 52 pre A's ( designed for but not accepted by the U.S. Army ), A polish Mosin copy, and a few Mauser actioned German, Belgian and French rifles. A photo of the Mauser's is shown below.
I have several other American trainers, but I think you get the idea of where my interest lies.
