Does anyone remember the old (i feel they may have been warne or talley) steel scope rings from the 80s and 90's that appeared to be all one piece? They were split in the center only on the bottom and you had to spread the ring over your scope then affix that nub into the base. They were fairly high end rings back in the day. I was looking for a pair and I can't locate them at all. Anyone remember who made those by chance?
