Wellll, WR rifles MAY not be the most reliable. To wit... My WR Boxlock was mfg. in 1908 for Jeffery Lyons in Calcutta (Lyons and Lyons). It came to the US sometime in 1950-60 where I became it's third US owner in 1995. It had been used in India for Tiger and I shot wild boar in California in 1997 and plains game, warthog and put a finisher into an elephant in 1998. As far as WR or I could tell, it had never been rebuilt.
It has hunted three continents.
It now resides in another person's collection. Selling that DR was one of my bigger mistakes I've made in a while as the new owner won't sell it back to me.

Oh ...I paid $6500 for it and original case (with the tiger hunter's name embossed on top) in 1995.

Fool!!!
