A lot of money has been spent over the years reversing modern scopes mounted on vintage rifles. Your rifle looks like it had a scope so should not be a problem, although I don't recognize the mounts I'm sure others might. Find the mounts first before you buy any scope.
Sometimes a rifle is desirable enough to have all the work reversed. This is a John Dubiel marked Mauser that had both receiver bridges drilled and taped, a modern scope mounted, the bolt bent and the bolt handle dished out, a new piece of wood inlayed across where the Lyman 48 was then re-inletted for the bent bolt. It was a mess, now unless I tell, no one would ever know. This quality of workmanship is way beyond my abilities, this was a job for an expert.
