Ok, i read some where years ago that the Curtis that worked for L.C.Smith had a high grade Smith made for the 10 guage and that it was made for upland shooting. Barrels were 28 inches and gun weighed 8 something as I recall,this was 20 odd years ago so I am not sure of the details. Has this gun surfaced? I think I read about it in Forest& Stream( I used to own a complete set)or in a book by the same Curtis,A. P. Curtis I believe.
