The thing is the difficulty in finding a proper gunsmith that really knows what he's about with these older rifles. Trying to mount modern scopes on them just isn't quite as straightforward as you'd imagine.
Even attempting to understand the mount/rings catalogues from EAW Apel & Recknagel I found to be a challenge. A damn good engineer would be fine as long as one knows exactly what to explain in terms of fitting the ironwork to the barrel/receiver but more especially lining up and machining the rear ring mount leg so the scope alignment is bob on gives a man a good headache.

Most older mounting systems that may accept a scope with a 1" tube are simply set too high so in my case, getting the objective lens close down to the barrel and mounting as low as possible has been the priority.

Hopefully all will be achieved and I'll enjoy a brilliant rifle scoped so that my aging eyes can view the quarry comfortably.
