Gun 2 defintiely appears to be a late Leman trade rifle. That does not necessarily mean "Indian Trade" - as Leman rifles like this were commonly sold and used all over the place as inexpensive working rifles - in the third quarter of the 19th century. I have seen a number that came out of the southern mountains. The architecture, mounts, lock, wrap around fore end inlay and artificially striped stock are all signatures of Leman guns of this era.
However, the tack decoration obviously looks Native to me; I just don't know enough about brass tacks to know if these look period or not. In either case, it appeasrs to be a Leman, ca: 1850-1870 era give or take.
