There is no confusion. The Fulton is a boxlock...the LC is a sidelock. Both were made in Fulton, NY, by either Hunter Arms Co. (early) or by the L. C. Smith Gun Co. (Marlin) later. Is the gun in question a boxlock or a sidelock? While still a good gun, the boxlock Fulton is only worth 1/3 to 1/2 as much as a field grade elsie in similar condition.
