In A (→FC,FE) there is no  lowering e to e in the last L.H. figure. The patent inaccuracy was corrected in GE and EE.

The version of A (→FE,FCGE1), without a  before the 3rd quaver in the bar, almost certainly resulted from Chopin's mistake, which is confirmed by the flats he wrote in FED and FES. In FC there is also no  before the 7th quaver, most probably due to an oversight, since in A the accidental is poorly visible due to the crossing-out showing through the page. Admittedly, both flats are visible on the photo of FC; however, they were added there much later by H. Scholtz, which explains the absence of the former in GE1 (the latter was added thanks to the  in the R.H.). The fact that those flats were added later is evidenced by their font (they are clearly bigger than the ones written by Fontana) and by the intensity of blackening, pointing to a pencil.

The sharps raising d3(2) to d3(2), overlooked in the manuscripts, were added in FE (→GE,EE). It is a typical inaccuracy of the Chopin notation.

b. 13

composition: Op. 28 No. 8, Prelude in F♯ minor

..

In A (→FC,FEEE1) there is no accidental before the 1st note in the last group. It must be Chopin's oversight – this and the next bar constitute a cadence in C major, and an enharmonic notation of degree 1 of that key does not make sense. A respective addition in the form of a flat lowering b to b was introduced in GE and EE2.
