My bases are reversed from the ones shown. The "ears" are at the rear and the wedge is at the front. Will your "ears" end interchange between the different rifles?
Apparently your rifle is not a Mannlicher-Schoenauer, but a break-open or falling block or a Mauser one. As I wrote, nothing is really interchangeable on these mounts. And, if you want to change the tops on the scope, even if to slightly different positions: The mounts are usually soldered to the scope tubes, sometimes even brazed, as I found out to my dismay. So you need someone able to completely dis-and reassemble these old scopes first. And, these Vienna Schnppermontagen are not the best mounts anyhow when it comes to stability and durability. Usually, windage adjustment can only be done by hammer and drift punch, slightly moving the base in the desired direction. So a simpler approach is to remove the existing bases, store them for later collector purposes and fit modern bases into the existing cuts.
