This fingering is out of tune - classical flutes intended to play in the third octave usually had extra keys, which allowed the designer more parameters to vary to maintain intonation over a wider range. The player was asked to play the fingerings 'where they were', rather than to tune them by varying the coverage of the embouchure hole. (The dimensions of the instrument are based on those of a large-hole Rudall and Rose flute: R & R #655 from the Bate Collection in Oxford.)
