Looks like a Springfield M1861/1863/1866 Rifled Musket and a Schofield revolver.

Edit: Or it can be a Springfield Trapdoor models, I can't really see the important bits. Somebody more perceptive than me may be able to tell them apart.

Further Edit: That's a Springfield Trapdoor, I can't tell which model but there's that breech block opening latch just besides the hammer there.
