The story is that the sax fingering were based on the oboe fingerings not the other way around. hope that helps

Ive seen a few of these up for sale on ebay in the past 3 years or so...they usually fetch a pretty penny, like around 2-3grand....but thats the only place where ive ever seen pictures of them....kinda funny that my conductor who plays sax refused to believe it is even a real instrument even after I showed him one of them lol....but they do! ;-)

Sounds kind of funky O-o

Woah, coooool.
