A couple people mentioned Mance Lipscomb's Boogie in A and Spanish Flang Dang earlier. Mance has quite a number of instrumentals.
There is also Sentimental Piece in G (which isn't particularly sentimental). And also Rag in F, which is a nice one. There are several others:
Rag in G
Blues in G
Mr Tom's Rag
Rag in A
Missouri Waltz
