The traces of a  visible in the L.H. part in A1 at the beginning of the bar show that Chopin started writing d here, yet he realised it quickly and wrote c.

d2 in A1

c2 in CJ, CK (→CB) & EL

The version of A1 featuring d2 is probably Chopin's mistake. It is indicated by a comparison with the melody of the song "The Wish", which is quoted here, as well as by the version of [A2] (→CJ,CK), in which the first two notes of the bar constitute a seventh (Chopin could have already heard the octave leap from the next bar).

CK is lacking in the  raising f1 to f1. This patent mistake was not repeated in CB; the remaining sources also contain the correct text.

The additional notes in the R.H. part present in b. 35-36 and 39-40 in CK – c2-d2, echoing an authentic ending of the melody in b. 32-33 – are most probably Kolberg's inauthentic addition, since they are absent both in A1 and CJ, based on [A2], just like CK. CB also confirms the lack of authenticity thereof – Balakirev did not see them in the copied manuscript that was either CK before the notes were added or another copy of Kolberg in which they were simply absent. These motifs, in an already elaborate form, appear in EL in b. 35-37 and – moved an octave lower – in b. 39-41.
