I got to wondering the other day about just what the differences are between the High Standard Models B and C.
I have a 6 3/4" Model B, and my uncle had one of the shorter (4½" ???) ones when I was a kid. I know they are chambered for the .22 Long Rifle, and the C was for the .22 Short.
Thinking about it, the only really needed changes would be the magazine, barrel, and maybe the recoil spring.
Just curious, it would make absolutely zero sense to try to convert a B to a C given the prices of .22 Short ammo these days.
