b. 16

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

..

In the main text we add cautionary flats to b1 and d2.

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

Crotchet b in A (literal reading→GEFE,EE,IE)

Quaver b in A, contextual interpretation

..

In A b, the top note of the tenth on the 5th quaver, is not attached to the G quaver, as a result of which it seems that it is separated from the quaver figuration and that it is a crotchet. This is how it was reproduced in GE (→FE,EE,IE). According to us, it is a misunderstanding – cf., e.g. the similarly inaccurately written R.H. sixths in bar 13.
The same applies to bar 34.

b. 17

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

..

In the main text we omit the unjustified  (cautionary?) to d1 at the beginning of the bar, present in all sources. On the other hand, we add a  restoring a1 on the 4th beat of the bar, omitted by Chopin. It was also added in GE (→FE,EE,IE).

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

Slur in A (→GEFE,IE) & EE2

No slur in EE1

..

The missing slur in EE1 is most probably due to the engraver's oversight, corrected in EE2.
