Bob, that is one magnificent rifle! Looks to me like a 'one gun collection' as Ruth Collis, the late secretary of the KRA used to say. Thank you for the great photos.
Brian, what style, school and so on is your long barreled smooth gun; any photos? Seems to me that you hold the record at the moment. Jim Whisker shows a 'one man three boy' long gun in some of his books, but I don't think that it was American made.
