303 British rifle

Hey all, I have this rifle that belonged to my Grandfather. My Dad believes that he had won it in a poker game back in the 60's. This is what i know. It is a Number 4 Mark 1* 1943 long branch rifle. It fires the 303 British round and doesnt have any sights on it. From what i understand it was used as a sniper rifle and was produced in Canada. Im wondering if anyone has experience with this rifle. I would like to put a scope mount on it but dont know where to get one. If anyone has more info on this rifle i would greatly appreciate it. I attached a few pics of it. Thanks.

There's not much left. The charger bridge is gone so the TO1 scope mount is out. There's bound to be some side mount but I don't know what it is. There's no sights or provision for them any more and the ejector screw is gone. It's more like an accumulation of parts. Is the barrel good? The problem with scoping those is the scope ends up so high you have your chin perched on the butt to see through the scope.

I took it to a gunshop to have it looked at. They said they didnt see any reason why it shouldnt be safe to shot. Before i do that im gonna have it checked out by someone who is more qualified in thesse types of weapons. Thanks for the info.

I have dealt with a few of these rifles in my time as an Armourer since the early 60's NWL and from the grainy fuzzy pictures, it looks to me like the butcher who chopped your rifle has also chopped off a substantial part of the right hand side locking shoulder. On that basis and using my No5 rifle experience, I'd say that it would be about as accurate as a piano. Scrap it for its parts value................. But that's only my humble opinion
