My preferred method (usually) is to make rings to fit the original bases and then to use a scope that's appropriate in power and appearance while also having excellent optics. The latter requirement is sometimes difficult to fulfill with older scopes and so I frequently use more modern glass, with few if any regrets. My main concern is to not alter the rifle in any way that could possibly be avoided, while retaining/restoring as much of its original appearance & configuration as possible.
Always bearing in mind that IMO functionality is far more important than appearance. I'll use vintage optics if in good shape and comparable to modern glass, but if the image is not clear and bright then I switch to a better scope regardless of appearance.
It shouldn't be too difficult to adapt available rings to fit the original bases shown, or even to make new bases to fit the original holes and then engrave the new setup to match. If done properly then the changes or additions would not be noticable to even the most discerning eye.
Good luck, Joe
