I am looking at three doubles with extra, extra long barrels. 36, 40 and 41+. Did the extra long barrels give any real performance advantage? Does the extra 6-12 give you a complete burn of all black powder? Were they just a sales gimmick like 25 barrels were fifty years later?
All guns seem to date to 1870-1880 time frame. They could have been for Swans or surface shooting waterfowl I guess, but not for walk up hunting. Weights come in at 10+ to 13 pounds. One 12 and two are 10s. Might have been for live bird shooting before they imposed a lot of restrictions on guns and loads. Long and odd looking.
