b. 3

composition: Op. 26 No 2, Polonaise in E♭ minor

..

The overlooked in A flats restoring A and a on the 3rd beat were added in FE (→EE,GE). Similarily in the subsequent instances of this bar – bars 51, 107 & 155 (in bar 155 correction omitted in FE).

There are no naturals rising a and d1 to a and d1 in A. Chopin's mistake resulted supposedly from a hasty correction—the composer initially marked the L.H. part in this bar as a repetition of the previous bar, and only after having spotted the diffrence on the 2. quavers of both bars wrote it out in full. The accidentals were added in FE1 and all the subsequent editions.

A has no  lowering d1 to d1 on the 3rd beat. The undoubted Chopin's mistake was corrected already in FE1, possibly at his direction.

A (→FEEE1) lacks  rising c1 to c1. The obvious Chopin's imprecision was corrected in GE and EE2, as well as in FES which displays  written in probably by Chopin himself.

composition: Op. 26 No 2, Polonaise in E♭ minor

..

Accidentals in A are to be found only before the first chord and a2-a3 on 5th quaver in R.H. All the necessary signs were added already in FE1, and repeated in the remaining editions (except for GE1 which overlooked  next to a3).
