Hunter made only two boxlock guns: The Fulton and the Hunter Special. There was also a Fulton Special (not to be confused with the Hunter Special, which was a different gun with the rotary bolt, which the Fulton didn't have.) But it was the same gun as the Fulton with a bit more "bling". Hunter did make a number of Fultons for Sears and other retailers, but the only difference in those guns was the name: Ranger, for example, on the guns they made for Sears.
It certainly was not Hunter that referred to any sidelock guns as "Fulton". From Hunter's 1921 catalog: "The 'Fulton' and the 'Fulton Special' guns are made to meet the demand for low-priced shotguns carrying our name and guaranty. They are reliable box frame guns capable of the most satisfactory shooting results. In finish, style and balance both out-rank their price. The 'Fulton Special' is the finer of the two in decoration."
