For years I've had the above. Never used it. Anyone have knowledge of this rig, or photos of it in use?
Unfortunately I'm in no position right now to take good photographs, as this rig is almost completely covered by other treasures. As far as I know, it is complete (with exception of the air valve that closes the air cylinder on the buttstock) and usable.
