b. 267

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

..

In A the flats were added in this bar in a visible haste, probably to complement the notation after the notes had been written. The signs before C and c are written a third too high, whereas instead of the necessary flats before g and c2 Chopin wrote signs before e and e1. The inaccuracy was not noticed in GE1 (→FE). The necessary signs were added only in EE and GE2, whereas the superfluous flats before e and e1 were removed only in EE

b. 311

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

..

In A (→GE1) naturals are written only before the 1st quaver in the L.H. and the 2nd quaver in the R.H. FE added a  before the 4th quaver in the L.H. (possible Chopin's proofreading), whereas GE2 – both necessary naturals in the L.H. It is only EE that includes the correct text.

b. 315

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

..

Similarly as in bar 311, Chopin wrote the necessary naturals in A (→GE1FE) only in the first triplet (in both hands). In this bar, the necessary additions were introduced only in EE and GE2.
