Two strokes pencilled into FED below the 3rd semiquaver of the bar are probably meant to make the barely visible ledger lines more distinct.

15 notes in A

14 notes in GE (→FEEE)

..

It is unclear whether the version of the editions, with the run comprising only 14 notes, without e2, should be regarded as an engraver's mistake or Chopin's correction. Unnatural spacing of notes in GE1 could point to a deletion of a note, however there are no visible traces of changes in print like tiny remnants of the original text. We thus adopt into the main text the undoubtedly Chopinesque version of A. Cf. similar problem in the 2nd movement of the Concerto, bar 80.

In all editions except GE2, this 14-notes long group is marked with a 15, left over from the A version.

b. 128

composition: Op. 21, Concerto in F minor, Mvt I

..

In A there is no accidental before the 2nd crotchet of the middle voice. It is certainly an oversight – dwas already at the beginning of the 2nd half of the previous bar, suggesting a modulation to E major (the suggestion is even clearer in an analogous phrase in bars 275-276). The naturals are explicitly present in the four remaining similar places (bars 40, 48, 136 and 284). The sign was added already in GE1 (→FEEE, →GE2), perhaps as a result of Chopin's intervention.
