You cannot make out what rifle he’s holding, or what pistol butt protrudes from that holster.
I think there actually is a lever there, but for some reason it is practically invisible. The bulge on the receiver just in front of the trigger guard has to eliminate Winchester and Marlin, and my guess is that it’s a rare Bullard Repeating Arms lever action. Bullards were made circa 1884 to 1891.
I also think those pelts are wolves.
