The earlier Noske mounts
http://www.worthpoint.com/worthopedia/r-noske-wwii-sniper-scope-mount-only-excellent had a unique split base rail that was spread by the two large capstan screws on top of the mount. This always seemed a better system to me than the typical lever/camming eccentric system which rely on a degree of 'slop' between base and rail to allow them to slide on and off. The two large taper-pointed screws also locked the mount in place very well. I suppose the only possible negative was that knurled capstan screws might have been a little hard to grasp for some people, hence the capstan bar holes for a pull through weight or something like that.
Did Noske move to the tapered rail and mount later, or were the different types concurrent?
The 'micro-adjustability' of the Jaeger mounts for eye-relief is excellent. I'm not aware of any other system that offers such a feature.
Thank you for sharing your knowledge and photos!
