Serial number overlap is a common thread thru-out Smith gun history; as we see this in the transition period from Syracuse address guns to those with a Fulton address, during the grades transition period after 1913, and with the Marlin acquisition. In fact, the serial number (210073, I think w/o checking the book) of one of the guns Brophy recapped as a Deluxe Grade, but oddly not the gun he identifies as the first Deluxe Grade, is noted within the pages of a ledger book from 1909-1910 (I believe that gun may possibly be one of the elusive A-4 Grades). I realize all this stuff is confusing; and although I, nor anyone else I know, have all the answers, we post here in an effort to share what we have learned (often from bad experiences) so that those who will be the future "torch bearers" for the Smith gun will have the benefit of our collective knowledge. Guns like the subject gun would be much easier to understand had that gun never received any restoration; but then we wouldn't have had the opportunity for this interesting discussion otherwise, would we? Again, I encourage those who collect to be ever watchful for the odd/unusual Smith gun; they are out there, they are great finds for the collector, and they are the primary reasons why collecting Smith guns is such an interesting and rewarding hobby. Again, I don't have all the answers; but I am always willing to share my opinion (for whatever a free opinion may be worth) with anyone who asks. By the way, the subject gun has great eye appeal; and, by eliminating the fore arm tip carving and replacing those hideout phillips head buttplate screws, one could enjoy a great-looking shooter that would always attrach admiring glances, as well as being a great conversation starter.
