Hey Ben.

All bore-rifles regarding doubles or singleshots are just rare, and they don`t become easier to find as time pushes foreward. The "bore"rifles have over the years attracted collectors because of the "hole" + they represent history of a the India/africa glamour period, when one could pioneer "uncharted" lands. Today if I wanted a pre-war double in nitrocaliber, I could get one tomorrow in any quality I can afford, but to find a bore-calibered rifle in high quality is much more difficult, because they are old(surviving rate small), they were used hard + rebored to smooth barreled + I don`t think that many were made as the doublebarreled counterpart....The ratio might look like 1 singleshot borerifle: 100 double borerifles...maybe even higher. Most of the really fine guns are among high-dollar collectors and seldom appear for public sale/auctions, before the collectors are dead, and the widow sales it for candy...haha. 90% of what is found on the internet and autions today on these borerifles are wornout, pitted, rusted and is circulated amongst the newbies to the gunworld, who has read about them once.
