Getting back to dovetail lumps.This Boss HG was built with damascus barrels.Almost all damascus guns were built with dovetail lumps even though an English gentleman named Henry Parsons patented chopperlump damascus barrels in the early 1860's and a few guns are out there,both double shotguns and rifles, built on his patent.Whether they were circumventing his patent,or there was an advantage to using dovetail lumps,this was the common method used with damascus barrels.With the introduction of Whitworth steel in the early 1880's and its heavy use by Purdey,chopperlump steel became the mark of a best gun.Going back to the very first post,that is why this gun has dovetail lumps,it was built that way.

Better to keep your mouth shut and be thought stupid,than open it and confirm.
