Stating the obvious, it must have been manufactured in 1897??? Short-Lived machine made gun.....

I think it was in the mid 1880s that S,D&G moved from 84 & 86 Chambers(Sloan's Sporting Goods Co. was @ 88 Chambers) in the mid 1880s??

Below is some text I lifted and I am not sure of its accuracy???

>> 302 Broadway NYC circa 1903. Moore's sold out to SD&G in late 1887 and they were located at the same place. The 12 story Building was Beautiful and known as the Vincent building, on the corner of Broadway and Duane street, and owned by the Astor family, and later owned by Fordham university in the 1940's. It was demolished in 1961.<<
