While browsing through previous Christie's auctions, I found this .450/.44 3" N.E. boxlock by R.Rodda for sale at an estimated price of 4,000 - 6,000 British pounds. (about $8000-11000) It remained unsold. The name of the auction was: "EXCEPTIONAL AND FINE SPORTING GUNS AND RIFLES", so I would expect the condition of the gun to be ok.
