you answered DAVID_BARNES' question about the bamboo sax. Indeed, the main part of that 'bamboo sax' I saw in Cologne was really a flute. I remember the photos that 'bamboo man' showed to interests. He was the one who travelled around the world in order to sell these flute-saxes, while his partner produced them in Hawai! where they had both a common little 'factory'.
I can't imagine that we are speaking of different persons. If I remember right, he named his instrument 'saxoflute' or the like.
