So, this is a bit of an oddball, but I have a fixed 6x42 Schmidt&Bender scope that I verified with the manufacturer via serial number, and instead of a 1", 26mm, or a 30mm tube, it is a 28mm diameter. I'm just wondering if anyone on here has ever encountered this unusual diameter, and if so, are there any rings floating around you could recommend. I've come up empty trying to figure something out, as the closest thing I can figure is that it was designed to have a 14mm dovetail rail mounted below it and secured to a rifle via some claw mounts, but it has no mount of any kind with it. Any thoughts would be appreciated!
