I picked up a 6.5 x55 MS Model NO carbine. It had an interesting pivot type of scope mount and I am trying to find additional rings for it.

I think the rifle came out of Sweden or area as I do have another 1952 MS with these same mounts and rings from that area. They are the rings I am showing here.

If anyone knows about these, who made them, makes them or any knowledge at all - I appreciate your help.

There are no markings at all on the bases or the rings.

Thanks in advance.
