Thanks Hawg, since i made the post i have taken the shotgun to my local gunsmith. It is his opinion that the gun is an early, original John Manton, and it is in "skeleton" condition (meaning stock needs to be replaced). Its definately a "fixer upper". Im discovering the world of fine european doubles and will have this one brought back too life. Whether or not its worth anything doesnt matter, it will probably never leave my possession, my sons, or my grandsons.
