Really like that you are using the book for inspiration. I need to do the same. Also, the missing bands add a lot to the horn. Gave a guy several banded horns to select one as a gift for a friend. He choose one that had one of the bands broken. Said the originals would have had broken bands and that was the one he wanted. You are pushing the envelope on these for the rest of us that play at making horns. Great horn.
