f1 in GC (→GE), FE3 (→FE4), EE & FESch

a1 in FE1 (→FE2)

..

The version of FE1 (→FE2) is certainly erroneous, which is proved by Chopin proofreading in FE3 (→FE4) and FESch. The correct version of EE can also be a result of Chopin's correcting the base text to this edition.

b. 59-63

composition: Op. 35, Sonata in B♭ minor, Mvt I

in GC (→GE) & FE1 (→FE2)

e in FE3 (→FE4), EE & FESch

..

The note present at the beginning of bars 59 and 63 in GC (→GE) and FE1 (→FE2) is the original version of the bass in these bars. Chopin changed them to e in the proofreading of FE3 (→FE4), in the base text to EE and FESch. In the corresponding bar of the recapitulation (bar 187), the fifth as the base of chord is present accordingly in all sources.

g2-c3 in GC (→GE), FE3 (→FE4), FESch & EE2

g2-e3 in FE1 (→FE2EE1)

..

The version with e3 present in FE1 (→FE2EE1) (in both FE without the necessary  in this situation) is almost certainly erroneous. It is proved by: c3 written in GC (→GE) and the Chopinesque corrections in FESch and FE3 (→FE4). The correct version with c3 is written inaccurately in some of the sources – the necessary  is only in GE and EE2. Further omissions of accidentals – see the adjacent note.

b. 219

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

The  raising c2 to c2 at the end of bar appears only in FESch (written in), FE4 and EE2. The absence of this accidental constitutes an undoubted oversight by Chopin in [A] – cf. e2 and not e2 in an analogous passage in bars 91-92.

b. 220

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

In FE1 (→FE2FE3) the 1st note in the L.H. is an A. The mistake was corrected in FESch, EE and FE4, the correct G is also in GC (→GE).
