A World System bassoon, but with a profusion
of duplicated tone holes and additional trill keys. In simple terms, the wing and boot are German system with addition of French keys; long is French with addition of German keys; French-looking bell is a compromise, having two tone holes. This very complicated bassoon has a total of 25 spatulas and one ring key, ultimately controlling 29 tone holes and vents, plus crook vent.
Sold as seen, no crook, in good condition, previously restored and colour lightened, chrome-plated. From the William Waterhouse Collection. Plays at A=440
