None of the Niedner scope mounts were patented.

They slid off just as the Noske and G&H do, the screws tighten the mount like the lever(s) on the G&H.

All scope mounts of this vintage had windage in the mounts, the German scopes only had elevation.

The Mauser above is a Niedner in .257-Roberts with a Shelhamer stock. When I got it over thirty years ago I shot a five-shot group with the Hensoldt scope, then removed and replaced it, every shot, for the next group, both groups the same size and same place.
