Dioptre sight mystery

The sight you describe as a "Walther Sport", was not a Walther sight, all Walther sights from early days to current ones have a clamp similar to the ones on the LGR set Bob sent you. All Walther sights old and new, are compatible on old and new Walther dovetails

What you describe is an Anschutz 6700 series sight, they used that clamping method for many years, and on any thing, even Anschutz's, it was common to see people trying to pry them apart with a screw driver to get them off! The common mod with them was to saw off the front half of the clamp so it was just on one thumbwheel and less bend so they still clamped OK but came off easier!

Thanks Robin.
Were there fakes around? The so called Walther Sport I saw was clearly marked with the Walther name. There was only one thumbwheel. A bolt on the LH side passed through the LH sight side and screwed into the thumbwheel; this was into a threaded 'tube' that was part of the thumbwheel and passed from the RH side of the sight across the dovetails. On fitting to the LGR, this threaded tube clearly just contacted the top of the LGR cylinder so that when the thumbwheel was turned the 'tube' in contact with the LGR cylinder moved the sight along the rails.
The mysteries deepen.

No Fakes, if it was marked Walther then it is one, or at least one of the cheapo Chinese ones they had made for a while and with drew, If the cross screw had a tube on it, it was either an LGV sight or small bore sight to lock in a grove which both had in the dovetail had to stop the sight moving under recoil. None I have had a squeeze up grip, and I have LGV, LGR, and modern ones, it may be some ones bodge up, or possibly a very early small bore sight. can you send a pic to my email?

Just done some research, some of the very early Walther small bore sights had a split clamp fitting, but its a real golden oldie, probably 50's!

Sorry, no photo. Golden Oldie (like me??). Does that mean it is valuable? Maybe I should try and acquire it?
The thumb screw was threaded 4mm and was a typical thumb screw with a threaded 'tube' extension about 6mm diameter (as part of the thumbscrew) that went through the rh side of the sight. The 4mm 'bolt' then screwed into this extension. The tube was long enough to almost reach the lh side of the sight, but not quite, so as to allow room for tightening the sides of the sight. The bolt was about 30mm long and was at some point, I guess, fixed to the thumbscrew extension by a clip to prevent the thumbscrew from being fully removed. Looking down the dovetail slots on the underside of the sight I could see that the tube extension was just visible along the dovetail grooves. This caused the tube extension to just contact the curved cylinder/dovetail top on the LGR. It may have been possible to reduce the outer diameter of the tube to give clearance for the cylinder. I guess about 0.25mm would have done it. On another point, it was not possible to get the sight on the LGR dovetail without springing them with a 'tool'. They could not be slid on from an end because of the position of the dovetail on the cylinder and the cylinder end cap.

Oh what fun.
