Skeettx: Thank you Sir.
That's more of what I would have expected from your Big 10. The more-pronounced bolsters (i.e., convex ribs) and the square barrel lug are the most obvious hallmarks of all the Syracuse Smith guns. The circa 1890 guns still have them too, but with now less-pronounced fullness and rounding on the breech balls (more angular), the 1891 guns have a wider bottom frame shape with much smaller "bolsters", and with a now-rounded barrel lug (the front part).
Evidently, a few 1892 guns also have these "transitional" features, but post-1893 guns do not exhibit any of those Syracuse-associated features and are fully flat-bottomed "Fulton" designs after that time. The late, great John Houchins (in his massive LC Smith tome) stopped counting these early Fulton guns in with the Syracuse production numbers at the end of 1892.
