L.C. Smith of Syracuse, NY and Hunter Arms Co. of Fulton, NY did not make a muzzle loading double gun, so we can be of little to zero help here. I suggest you visit the doublegunshop forum and check with the pros there. When doing so, be sure to post good detailed pix of your gun; and clear pix of all stamps on the undersides of the barrels when they are removed from the frame. Just guessing, but I'd think this gun may have been made by a English gun maker; and the brass door in the stock was the cover to what is known as a "patch" box.
