There is no  raising d to d in A (→FEEE1). Chopin's patent inaccuracy was corrected by Fontana in FC (→GE); a  was also added in EE2 (→EE3).

b. 455

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

..

In A the only accidental before the 1st chord in the R.H. is the cautionary  before e2. From the musical point of view, the version with dwould be possible, yet a comparison with analogous bar 425 and a  of d3 added – probably by Chopin – already in GE1 (→FEEE, →GE2) prove Chopin's mistake. Chopin committed the same mistake in a similar context in bar 423.
In the main text we omit the unjustified  before e2.

b. 462-463

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

e3 in A (literal reading→GEFE1)

e3 in A (contextual interpretation) & FE2

e3 & e3 in EE

..

Just like in bars 422-423, the flats lowering e3 to e3 and the cautionary  before e2 in the L.H. in bar 463 prove that the version of A (→GEFE1), interpreted literally, is erroneous. In EE, a respective  is only in bar 463 (together with a  before e2), which is probably a result of an oversight of the sign in bar 462.

b. 470-472

composition: Op. 39, Scherzo in C♯ minor

 d3 in EE & GC (→GE)

No accidentals in FE

..

In FE no naturals lowering dto d3 in b. 470 or d2 to d2 in b. 472 must be seen as errors, which is further confirmed by their lack in GC, despite the fact that Chopin personally filled them in. Naturals in EE may have been added based on the previous three corresponding occurrences of this phrase (bars 176, 220 and 308). Sharps in bars 445447466 also show that  Chopin was not sure over a longer phrase if  (d) belonged to the key signature.
