Very cool specimen. It is hard to make a Flute that long without ending up with a step or hinge. I have often wondered what exact method they did indeed use since we can only guess and derive our own methods.
careful deriving. not supposed to drink and derive but some do it anyway claiming it sharpens the mind and the flute. speaking of flutes did you hear about the Neanderthal who stepped on a hinge while performing the flute stoned? yea...mammoth fail. guess you had to be there.
