G'Day Fella's,

Thank You Louis for sharing the above images and details with us.

It's not until you see images of older firearms like this Mauser Mm 410 B rimfire, that you get a better understanding of where Brno may have taken some idea's from, for their Model 1 rimfire.
I'm not saying that the Brno designers did, it's just that there are several similarities, between this older Mauser, and the Brno Model 1 (and the Model 2, etc) ..................

D'oh!
