b. 52-60

composition: WN 17, Polonaise in B♭ major

Arpeggio sign in JC

Arpeggio signs in EF

No signs in PE

..

In the earlier sources, some of the chords in the L.H. on the 3rd beat of bars 52 and 60 are provided with an arpeggio sign: JC has a wavy line in bar 52, while EF – in both. It is hard to determine what was Chopin's intention in this regard. Lack of wavy lines may be explained by an oversight, their presence – by a mistake resulting from a similarity with bars 53 and 61, and in the case of EF also from a generalising revision. It is also possible that Chopin changed his mind: at the time of writing [AI], he predicted arpeggios each time, while in [A] – already not. In the main text we give the version of PE without arpeggios.  
The same applies to bars 88 and 96, which are repetitions of bars 52 and 60.

Accent in JC

Accents &  in EF

Accents in PE

..

We give the accents appearing in PE over the chords on the 3rd beat of bars 52-53 and 60-61, which are beyond any source and stylistic doubts, in the main text. In JC, there is only the first of them, which is most probably meant to be understood as a draft suggestion of the same notation. The version of EF with  markings, which Chopin used only occasionally, must be considered to be non-authentic in this situation.

b. 53-61

composition: WN 17, Polonaise in B♭ major

3 arpeggio signs in JC

4 arpeggio signs in EF & PE

..

In JC, lack of arpeggio in the R.H. in bar 61 is probably a result of an oversight. All wavy lines in JC are put on the right-hand side of the chords.

b. 53-61

composition: WN 17, Polonaise in B♭ major

Grace notes G1 in bars 53 & 61 in JC & EF

No ornaments in PE

..

There is no reason to question the authenticity of any of those versions. Chopin most probably resigned from the Ggrace notes, while writing [A] (→PE).

b. 53

composition: WN 17, Polonaise in B♭ major

..

In this bar, JC has two additional notes, which remained here as a result of an erroneous insertion of the 2nd group of four notes from the subsequent bar. The enote was removed, b1 i c2 remained despite adding the correct text. Also the unjustified in the context of quaver rhythm dot extending d1 on the 2nd beat of the bar remained. It is possible that the lack of a crotchet stem next to the note is also related to the described error.
