As in b. 35-36 and 39-40, in the manuscripts Chopin overlooked some of the necessary accidentals, in this case only flats. AsI lacks a  to the 14th semiquaver in b. 43 (g2) and to the 10th semiquaver in b. 44 (g), and A lacks a  to the 14th semiquaver in b. 43 (g2) and flats to the 8th and 20th semiquavers in b. 44 (g1 and g). All omitted accidentals were already added in GE1, which was repeated in the remaining editions. In the main text, we omit the unnecessary repetition.
In the AsI notation, attention is drawn to the unnecessary repetitions of flats before g3 in bar 43 (as in A) and g1 in bar 44, as well as 3 flats (cautionary?) before e3 in bar 43 and e2 and RH. e in bar 44.
