OT Brno Question

[John303]

The significance of the Brno 21 & 22 designation is all over the place, barrel length, stock length, etc. etc. I personally believe it is the action, round (21) versus the two square bridges with integral mounts (22).
Can't find any reference material to confirm anything, anyone out there got any and or can direct me to some, a catalogue or something.
Thank you for any response. --- John

Interesting thought! I know the H and F were stock length, and have thought the 21 and 22 we the two barrel length designations. I have a 21F, full stock, 20 inch barrel round checkered action.
Best,
Craig
