b. 243

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

..

In FE the last chord has a quaver stem. The absence of rest, required if the chord was shortened, proves that it is a mistake, probably stemming from a misunderstanding at the time of implementing extensive proofreading of pitch and rhythmic values in bars 243-244.

b. 243

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

..

In A there is no  before the 1st crotchet. The patent inadvertence was corrected in GE (→FEEE).
In FE there is no  lowering g to g on the 2nd beat of the bar. It must be a side effect of an inaccurately implemented proofreading of the part of the L.H. encompassing bars 243-244. The mistake was corrected in EE.

b. 243

No mark in FE (→GE,EE)

Accent suggested by the editors

..

Just like in b. 223, in the main text we suggest adding an accent at the beginning of this bar after b. 227 and 247.

b. 243-247

composition: Op. 22, Polonaise

e1-a1 in FE (→GE) & EE2

e1-a1 in EE1

..

Just like in b. 223 and 227, the version of EE1 in b. 243 and 247 is probably Chopin's mistake adopted from a proof copy of FE. The natural raising a1 to a1 was added in both bars in the penultimate stage of proofreading of FE (→GE). The correction was also introduced in EE2.
