Fulton Arms Co. shotgun??

[Arachnid]

Hello all, I have a single shot shotgun
that has Fulton Arms Co. stamped on the
left side.Also when you break open the
gun, on the left side of the barrel you
can read.. patented Aug.11 1898 you
can only see this if you open the action.
The only other markings on the gun is the
number 12 stamped under the bottom side of
the barrel, where the forearm stock is.The
gun is in rough condition but I was wondering
if anyone had any information on this gun.
Sorry if my words to describe the positions
of the gun are wrong but I really do not know
alot about shotguns.Thanks....Kenneth
