Easy to tell if it's a Fulton and not a Stevens. A Fulton will have 3 large slotted screws set in the bottom of the receiver, in a triangular arrangement. If it doesn't have those, then it's likely to be a Stevens--although I think we also confirmed in the past that there were some Nitro Specials sold under the Ranger name. (I've never seen one of those, but I have seen several Ranger-marked Fultons.)
