O. Mauri was a Milanese flute maker active between the late 19th and early 20th centuries. His instruments, produced in small series, are crafted with great care and are considered extremely rare. Here I present a beautifully crafted wooden flute descending to B, with the extra keys SI-DO, LA-SOL. Closed G♯, A 440, weight 537g. The flute is very good condition, no cracks, complete; it needs new pads.In this site you will also find a metal flute by Mauri.
