Sure sounds like a "Redfield" type that us yanks use. I say "Redfield type" since quite a few other companies besides Redfield make these bases. Leupold and Burris also make this type of base mounts. Redfield uses a mark on their mounts with is an "R" in a cirle. Good luck-

I was just putting some mounts back on a rifle I sold to a mate when I broke a screw that holds the rings on. I don't know what type of mounts they are but the front rings turn into their recess and the rear are held on by two screws (one of which I broke)The screws fit over the "dovetail" on the ring itself and I'd say are the windage screws. Any thoughts to the brand?

Its on an old spanish mauser 93. Its a bridge mount with two screws at the back and one at the front.

It's a old Hilver bridge mount to suit Mauser 95 and replacement screws are like rocking horse shit, these days.
Where do I send your replacement?
