I am going to side with the Spencer ID. In fact, it looks exactly like this one being held by Geronimo. If you notice the scuffing on the butt, I think this is the rifle you have. Not one "like" it, but the actual rifle that belonged to Geronimo before he was captured and jailed at Ft Sill, OK.
With a provenance such as that, it could easily be worth 100K or more.
