b. 21

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

..

In A there are no naturals raising d3(2) to d3(2). Chopin's patent oversight was corrected (perhaps by himself) already in GE (→FEEE).

b. 22

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

..

In A the naturals raising d notes to d are written only on the 4th beat of the bar. In spite of this, there are no doubts that d is required in the entire 2nd half of the bar. In GE1 (→FEEE, →GE2) a  raising d3 to dat the beginning of the 3rd beat of the bar was added (referring also to d4), but only EE and GE2 include a corresponding sign before the penultimate semiquaver.
