b. 16-18

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

..

In the main text we add cautionary flats before the d2-d3 octave and before b in the middle of bar 16, e in bar 17 and a in bar 18.

b. 17

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

..

In A (→GE) Chopin overlooked the  returning bin the last crotchet in the bar. The addition of the sign in FE (→EE) may be assigned both to Chopin and a revision of the editor.

b. 19

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

..

A (→GE1) includes a repeated  before the top note of the octave. The superfluous sign was removed in FE (→EE) and GE2.

Staccato dot in A & GE2

No mark in GE1 (→FEEE)

..

The missing dot in GE1 (→FEEE) is certainly an oversight of the engraver.

Slur from crotchet in A & GE2

Slur from 1st quaver in GE1 (→FEEE)

..

The earlier beginning of the slur in GE1 (→FEEE) is certainly erroneous and it was corrected in GE2 after A.
