Wtb- Bausch and Lomb Balvar scope rings and mounts.
Bases to fit which rifles?
Ring sets to fit which series of bases?
Not all ring set designs will work with all base styles. The early base styles will work with both the plunger style rings and the "clamp-ring" or "spring" style rings, but the later base styles will only work with the "clamp-ring" or "spring" style rings. B&L never actually made the bases, they were contracted out to Kuharsky, Bros., in Erie, PA. When B&L decided to discontinue the Balvar adjustable bases, Kuharsky continued to make them under their own name. When Kuharsky stopped making them, somebody in PA or OH made them under the name PIMM.
I have several plastic storage boxes full of B&L, Kuharsky, and PIMM bases and ring sets, many of them duplicates, so I might be able to help you. PM if you're interested.
