..

GC and FE1 (→FE2EE) lack in the accidental before the 3rd crotchet in the L.H. Patent in this context Chopin's mistake was corrected in GE and FE3 (→FE4). Moreover, FE1 overlooked the  before the 4th note.

Minim & semibreve in GC (→GE)

No inner notes in FE1

Minims in FE2 (→EE,FE3FE4)

..

In the main text we give the undoubtedly correct rhythmic notation of the middle notes of the chord, transmitted by GC (→GE). Among the remaining versions, the first is erroneous, whereas the second – inaccurate (probably due to a misunderstanding of the notation of [A]).

2 slurs in GC, GE2 & EE

1 slur in FE

No slurs in GE1

..

The absence of slurs in GE1 is undoubtedly an oversight of the engraver, rectified in GE2. The FE version also results most probably from the engraver's mistake. The slur omitted in FE was added in EE, perhaps at Chopin's request.

b. 137

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

2 different slurs in GC

No 2nd slur in FE1

2 different slurs in FE2 (→EE,FE3FE4)

2 half-bar-long slurs in GE

..

The inconsistent with the bar stucture L.H. slurring in GC as well as the lack of the second L.H. slur in FE1 are almost certainly mistakes by the copyist and the engraver. On the other hand, the slur added in FE2 (→EE,FE3FE4) is probably inaccurate, as evidenced by the slurring of the subsequent bars. In the main text, we give the probable reconstruction of the slurs in [A], aptly guessed in GE.
