b. 126

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

..

In the main text we add cautionary flats before e2 and e3.

b. 126-127

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

1 slur in A & GE2

2 slurs in GE1 (→FEEE)

..

Breaking the slur between these bars is a characteristic inaccuracy of the engraver of GE1 (after all, the two-bar slur in bars 125-126 is already a result of proofreading – the remaining elements of original slurs show that each of these bars was most probably embraced with a separate slur). The continuous, four-bar slur written in A was restored in GE2. See also bars 128-129.

b. 128-129

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

Slur up to bar 129 in A & GE2

Slur to end of bar 128 in GE1 (→FEEE)

..

Ending the slur before the last note of this passage in unison is certainly an inaccuracy. Both changes to which the slur of A was subject in GE1 are deformations typical of the engraver of this edition – dividing a long slur and adjusting it to metric structures.

b. 131

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

No indication in sources

[Viol.] suggested by the editors

..

No indication of the change of the leading instrumental group is almost certainly Chopin's oversight, caused by the transition to a new page in A. Four bars further, the composer marked an analogous change.

It is difficult to say what the ccrotchet (grace note?), written in A over the d1-esecond at the beginning of the bar, means. It is not corresponded by any note in Morch, it was not included in the editions either. In this situation, we regard this inexplicable, from the point of view of melody and harmony, note as a mistake.
Perhaps it was to be an e3, sustained from the previous bar, in which the e3 minim is provided with an additional curved line. However, the curved line is not combined with the discussed note, hence we do not include this possibility, doubly hypothetical, in our system.
