b. 290

composition: Op. 49, Fantaisie in F minor

..

In FE1 the accidental to the bottom note of the 1st R.H. chord is missing. The sharp was added by FE2.

b. 290

composition: (Op. 4), Sonata in C minor, Mvt IV

Wedge in A (→GEIE) & FE2

No mark in FE1 & EE1

Staccato dot in EE2

..

The missing wedges in FE1 and EE1 are probably oversights, corrected in FE2 according to A (→GE), and in EE2 imprecisely.

b. 291-303

composition: Op. 39, Scherzo in C♯ minor

Beginnings of slurs in EE and FE

Slurs in GE

..

As far as beginnings of slurs in bars 291 and 299 are concerned, we decide to give priority to the consistent notation of EE and FE, without trying to reach final conclusions about Chopin's intentions in that respect. In GC, and partly in GE, the slurs in those bars run from the 1st crotchet . GE also has arbitrarily added slurs in the L.H. part.

b. 291

composition: Op. 39, Scherzo in C♯ minor

..

In EE, the octave at the beginning of the bar is notated in the abbreviated form with 8. This is probably an arbitrary change  that was introduced due to lack of space.

b. 291

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

Wedge in A

No mark in GE1 (→FEEE)

Dot in GE2

..

The missing staccato sign is certainly a mistake of GE1 (→FEEE). In GE2, in spite of the clear wedge in A, a dot was added.
