b. 9

composition: Op. 10 No 10, Etude in A♭ major

No fingering in A (→FE→GE)

Fingering in EE

The fingering, added by Fontana in EE, repeats in both hands the schemes given by Chopin in bar 1.

b. 10-14

composition: Op. 10 No 10, Etude in A♭ major

..

The cautionary  before e2 at the beginning of bar 14 was added in the proofs of FE (→GE,EE). We also complement a corresponding accidental in an analogous place in bar 10.

 in A

No sign in FE (→GE,EE)

Our variant suggestion
..

An accidental omission of the  mark in FE (→GE,EE) seems to be much more probable than Chopin's proofreading.

b. 13

composition: Op. 10 No 10, Etude in A♭ major

..

The lack of naturals before the sixth on the 6. quaver is an undoubted oversight by Chopin in A (→FE). The  before the upper note was complemented in both GE and EE, however the one sharpening d2 to d2 was only added in GE2 (→GE3→GE4). The lack of the latter accidental also infuences the pitch of the penultimate quaver of the bar. This inaccuracy was noticed during the proofreading of FE (→GE,EE) where a  was added before that quaver.
