Enclosed are images of which I believe to be a fowling gun which may have been sold by a ironmonger which was common in that period It is Birmingham made and proofed with a 33inch Damascus twist barrel which would have been 40 inch's or more and in good condition with no bore pitting .Although muzzle loading shotguns were made in all bore sizes with this one it is a 7 bore and not a common size the lock is back action which would put the gun in the late percussion era and a pistol grip style of a trigger guard You will find that there were a lot of these big bore guns which had the barrel reduced to 30 -32 inches for the sport of live pigeon shooting from traps
