Max Brand's Westerns. It's a shame your uncle won't read e-books, as a lot of Brand's work is cheaply or freely available in digital form, but you'd probably be able to find a lot of titles in thrift stores if your library doesn't have them.

P.S. I glanced at your library system, and it looks like it has a significant number of Max Brand's books, including many in large print, if that's a factor.
