The third quaver in FC is incomplete and, hence, illegible. One can see there traces of an unfinished correction – the note head of the A
note was deleted, most probably together with the 
placed in front of it (which gives A
), however, there is no note written instead of the deleted one. GE1 decided to print in this place A; in this version the 5th quaver, devoid of the accidental, is an F. In turn, the reviser of GE2 (→GE3) added a in front of it, raising it to F. None of these versions can be authentic, which is confirmed by the compatible text of FE and EE with F on the third, and as a consequence, 5th quaver. According to us, it is most probably this version that was the only one written by Chopin and if it had not been for the so-called Terzverschreibung error committed by the copyist, it would have been included also in FC.
