No accidental (b1) in GC, FE & EE1

Flat (b1) in GE1

The notation of this bar is erroneous or inaccurate in the majority of the sources. Most probably, Chopin, writing this fragment in [A] for the third time (after analogous bars 6 and 25), had already such a strong correlation of the notes with the proper sound that he did not notice the missing  before the 4th quaver. Cancelling this alteration was, as usual, obvious, hence it was not marked even when the composer would correct the notation of this bar in FES (AW also does not include the ).

The cautionary  added before the 4th quaver in GE1 is certainly an editorial revision (most probably erroneous).
