b. 291-292

composition: Op. 2, Variations, complete

Staccato dot & slur in A

2 wedges in GE (→FE,EE)

Wedge in FESB

..

The version of the editions most probably resulted from revision and a mistake by the engraver of GE1 – after putting legato and the R.H. slur between the staves, there was no space left for the  hairpin and the L.H. slur. He placed the hairpin under the stave and most probably forgot about the slur, which, moreover, was quite inconspicuous in A. In this situation, it is difficult to consider the additional wedge authentic.
FESB overlooked the first wedge.

b. 291-293

composition: Op. 49, Fantaisie in F minor

Pedalling in A (→GE)

No markings in FE (→EE)

..

Chopin most probably added pedal markings to A after [FC] had been finished, which explains their absence in FE (→EE).

2 slurs in A

3 slurs in GE1 (→FEEE)

Slur in GE2

..

The division of the clear slur of A is a typical example of the manner of the engraver of GE1 (→FEEE). In the main text we omit the additional slur over the quintuplet written in A – General Editorial Principlesp. 16.
