Hello All,

I just acquired an 88 Sporter (?) Variation w/ a rare scope mounting. The scope pivots to the side, and the whole assembly is also claw-mounted. Pushing the button "up" on the left rear of the mount, removes the scope.

The scope itself is held in a "clam-shell" arrangement with a thumb screw. There is a "V" notch in the mount that aligns the scope into a similar "V" on the rear scope ring, so that it always returns to the same "rotation" if removed. The retical is a strange crosshair-post configuration with a small "loop" at the top of the post.

I could use some help to determine what exactly I have. There are lots of markings on the barrel and action. No caliber marking but chamber cast shows 8x57 with a .319 bore.

Here are a lot of pictures:
