I have a circa 1874 W.W. Greener double barrel shotgun. It was made in Birmingham England. It has double hammers with nice engraving. Greener shotguns are still produced today but in limited numbers.
Riverside shotguns were made by Stevens. I'm not sure when they started and stopped using this name, but the Riverside hammergun should be the Model 215 which was produced from 1913-1932.
