So I was at Southeastern, and they had someone give them a large amount of music a few days ago, (it was mainly French Horn Concerti) this was in it. I'll try to upload a picture of the cover, and then see if I'm able/allowed by Conn to copy the whole thing.
EDIT: And it's already on the internet: http://www.saxophone.org/museum/publications/id/248
Still interesting, though.
