Hi a friend of mine who isn't on here is looking at a secondhand Selmer Series III. She's found two in different places that are massively different prices - the really expensive one is labelled on the website as Dragonbird, the cheaper one isn't. Before she trots off to see and play them she asked me whether I knew what it meant. I haven't a clue but I said I thought you lot may. Is it a limited edition version? Google says it's something to do with engraving and a Charlie Parker tribute, but are all Series III after a certain year Dragonbird or not?
