b. 102-104

composition: Op. 49, Fantaisie in F minor

..

In the main text we add a cautionary  to a in bar 102 and to b in bar 104. The latter is also in FE (→EE), perhaps added by Chopin while proofreading FE1 or earlier, to [FC]. In an analogous harmonic context, in A Chopin wrote cautionary accidentals in bar 271, 273 and 275.
Moreover, in bar 104 we add flats to the A-a octave.

b. 105

composition: Op. 49, Fantaisie in F minor

In A the naturals raising d2 to d2 and d1 to d1 are missing, which is a patent oversight. All editions contain the correct text.

The fact that the missing naturals in A (→[FC]FEEE1) resulted from Chopin's mistake is proven by the harmonic sequence in analogous bar 273, featuring an E chord, and not an E minor chord, as well as by the regularity of the R.H. major third chromatic sequences in bars 101-109.

b. 106

composition: Op. 49, Fantaisie in F minor

..

In A one can see that Chopin initially wrote the 3rd L.H. crotchet an octave higher, as B-b.

b. 108

composition: Op. 49, Fantaisie in F minor

..

In the main text we omit the poorly justified cautionary  to d1 in the chord on the 2nd crotchet in the bar. A respective accidental was already put to d3 in the R.H.
