A lacking  before the penultimate quaver is most probably a mistake by Chopin. The accidental was added by the revisers in both GE and EE.

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.

No sign in A (→FE)

In this context, the missing  mark is undoubtedly a result of Chopin's inattention, who added pedalling in a proofreading of FE, or – which is more plausible – of the engraver implementing this proofreading. The mark was added both in GE and EE.

We add a cautionary  before a1. The sign was already added in GE2 (→GE3→GE4) and EE4.
