This fingering may be considered as E4 with a register hole. The fourth minimum produces E6. The 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 dimensions of this instrument are based on those of a large-hole Rudall and Rose flute: R & R #655 from the Bate Collection in Oxford.)
