TubeNet

This may be a long-shot, but is there anyone out there (band directors with old solos in your band library or fellow tubists) that has a copy of the tuba solo “Down in the Valley” by Harold L. Walters? It is presumably a fairly easy level tuba solo (class 3 in Texas), but it is permanently out-of-print, and I’d like to add it to my music library if possible. I’m willing to purchase it, or trade for it.
