The natural raising d2 to dappears in A (→GEFE1) only before the 13th semiquaver. The mistake was corrected – most probably by Chopin – in the proofreading of FE2 (→EE). In the main text, we omit the  on the 13th semiquaver of the bar, superfluous in relation to the sign on the 4th semiquaver.

b. 244

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

..

The bar is not written correctly in any of the sources. In A four signs are missing: a  before the 5th semiquaver (d2) and flats before the 7th semiquaver (b) and before the last two semiquavers (b2 and d2). In GE (→FEEE) only two signs were added: a necessary  before the 5th semiquaver (d2) and a cautionary  before the 14th semiquaver (d3). Moreover, A repeated a  before the bottom note of the last quaver in bar 244. The unnecessary sign was removed in EE1 (→EE2) and in GE2, but it was restored in EE3.

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

There are no accidentals in the last group of semiquavers in the L.H. in A. In GE (→FEEE) the signs were added after the R.H. An authentic cautionary  before a2, in the editions added also before a1, draws attention.
