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.

Probable long accent in A

Possible short accent in A (→GEFE)

Vertical accent in EE

..

It is unclear which type of accent Chopin meant here. The sign is shorter from all previous ones on this page of A (bars 289-290); however, its shape is characteristic of long accents – cf. the accent in bar 293. GE (→FE) has a short accent, which in EE was changed to a vertical sign.

b. 291-294

composition: Op. 11, Concerto in E minor, Mvt I

..

In each of these bars, in FE, there is a  before the 1st semiquaver in the L.H.; however, in the further part of the passage, respective notes in other octaves are devoid of marks (except for the  before in bar 293). These patent inaccuracies, repeated almost certainly after [A], were corrected in the remaining editions.
