The Roosevelt Sykes United sides (with Porter on guitar) are good stuff - also don't miss Remo Biondi's bluesy violin. All are included on Delmark 642 - Raining in My Heart.
I think that saxophone and guitar are an unusual double. Perhaps I'm just not thinking, but offhand I can't remember another case like that. I know Little Walter recorded on both harp and guitar, but that's at least a bit different. Probably someone will come up with an obvious example that I overlooked.
