The missing grace notes opening the trill are almost certainly Kolberg's mistake, who interpreted them as a . This version was copied in CB and EL, yet Balakirev omitted the , completely superfluous in this context (on the crossed-out first version of the last page of CB, one can see that the Russian composer started writing this , yet after putting the first vertical line, he realised that it was pointless here and abandoned it).

We consider the accent under the grace note in CK to be an inaccurately written  hairpin. This is how the mark was interpreted by Balakirev in CB. The mark, musically unjustified, was omitted in EL.

The version of EL is probably Kolberg's revision. However, one cannot rule out a mistake (e.g. of the engraver) due to the resemblance of the accompaniment in b. 55-56 and 51-52.

Unslashed grace note in A1 & CB

Slashed grace note in CJ, CK & EL

..

In #A one can see that Chopin initially provided the trilled note with the value of a double dotted minim, whereas the c2 note ending the trill – with the one of a quaver. It was still in A1 that he changed it to a semibreve and a non-slashed grace note. Therefore, the notation of [A2] featuring a slashed grace note, confirmed by CJ and CK, may be considered the last stage of the process of delaying the moment of playing the final c2 note. However, the difference in the notation of the grace note does not have to be meaningful, since in the Chopinesque notation both versions can be equal.
