Not original stock for sure, I have a 1954 Brno in 7x57, double set triggers, butter knife handle with an original factory scope. The scope does not have see through mounts and the mounts are integral to the scope. One can remove the scope very quickly by loosening the mount screws and pulling the scope back off the dove-tails, there is a pin on the mount to keep going to far forward in re-mounting the scope. The scope is mounted very low and comes up perfectly. I have not seen another so I would guess that the scopes matched to these rifles are rather scarce. I looks in this case one problem created another - too high mounts and so on. FYI--- You can see an "original" Brno sans scope by going to Tradeex Canada. --- John 303.
