I'm not sure what this thing is. It says "Marlin" on the barrel, with a patent date of 1887. It also says ".38w", I believe this means it's a .38-40. Serial number is 19726
I'm pretty familiar with Winchester lever actions, but I have no experience with Marlins. All the Marlins I've ever seen were "side eject", this one is a "top eject".
It's missing a couple of parts inside the action, like the piece that lifts the rounds from the magazine up to the chamber (not even sure what that part is called).
This rifle is belongs to my Girlfriend's Dad. We're planning on fixing it for him for his birthday, and I'd like to know more about it. Info like what model, what year was it made, how much is it worth, and so forth. Thanks in advance.
