b. 121-123

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

No sign in GC (→GE) & FE1 (→FE2EE1)

 in FE3 (→FE4) & EE2

..

Chopin added the over two-bar-long  hairpin in the proofreading of FE3 (→FE4). It was also repeated in EE2. Similarly in bars 129-131.

b. 121-122

composition: Op. 64 No 3, Waltz in A♭ major

No pedal change in A

Pedal change in FE (→GE,EE)

..

The pedalling of FE (→GE,EE) is certainly erroneous.

b. 121-122

composition: Op. 64 No 3, Waltz in A♭ major

Slur in A (→FEEE)

No slur in GE

..

The missing slur in the L.H. in GE is most probably a result of an inaccuracy of the engraver of FE, who overlooked this sign (A is poorly legible in this place due to deletions). In the last proofreading of FE (→EE), the slur was added, probably by Chopin.
