Igor, the rings appear to be the later central pin type rather than the earlier offset pin type which is what our customers had. They also only have a limited size range. Our customers would bring us their scope of choice and we made rings specifically to suit their scope, quit often period scopes, and importantly the rings are made to suit the position of their bases so that their is no stress on the scope. We also made our rings with a vertical split which helps with bolt cycling as it gives the greatest finger clearance.

By the way, thanks for posting that website, looks like they make a good product. I notice the actions have a full recoil lug rather than the small factory lug.

Waidmannsheil.
