I have a R&S (Euroarms mfg) purchased around 1980. Nicely finished, feels nice in my hand, superior design. Never shot it ... reason unknown but I'm glad I didn't. It is now a "closet queen," for display only.
Some disagree with me on this, but shooting any BP firearm very slowly degrades it. I enjoy shooting modern replicas as they can be reproduced again, but this mint replica is, at least in my mind, mostly in the same category as a vintage arm. (Shoot it, disassemble to clean, re-assemble, oil it ... it all takes its toll.)
Too bad the R&S design was too late for the CW, maybe too early for the cartridge era.
