This instrument is made up of three pieces in ebony, with burnished nickel-silver rings and keys. It is one of the few flutes with a Böhm system to be found at the Sforza Castle; this evidences that this system has made a success in Italian production only starting from the early decades of the 20th century. Ambrogio Bernucca, the manufacturer of this flute, was awarded the bronze medal at the International Exhibition of Milan in 1906 as chief installer of the company Barlassina & Billoro, which specialised in the production of flutes featuring the Böhm system. In the 1920s Bernucca’s "Boehm company of cylindrical metal and wood flutes" was based in via Melzo 11, Milan.
