In my trawl through 50 years of back catalogues, from the Big 4 London auction houses, to the trade auctions, and small regional auctions, I come across many great double rifles.....for instance, back in May and July catalogues for Weller & Dufty, there are some supreme examples by Purdey, Henry, Boss, Grant etc etc. Sadly, many lots are not photographed, and those that are, are black & white. The catalogue descriptions are very good, as the cataloger was Doug Nye, for my money the best in the business at the time.
