the rings are post WW1 made or sold by August Kinder (AKAH).that type logo was used in the early 1920s.
the chances of locating a set of bases close enough to fit the rings to will be next to impossible.
the claw mounts were originally built up from the bases.the front ring was actually a press fit as new and needed to be pried apart.i have some never used prewar claw mount front rings that look the same but the rings are not interchangable with the bases.the windage blocks on the rear rings were never finished untill the front ring was installed on the rifle and the scope could be lined up.
i had about 75 pounds of new claw mounts and bases and used rings and used bases.only found one used front ring and one used dovetail base that could be fitted together.none of the rear bases were the same height even though they were made similar.
took a double handfull of used rings,that i was going to scrap out,to a show and ended up trading them for a mauser rifle.
