..

In JC, there are no flats lowering a and a1 into a and a1. The undeniable oversight of Chopin in [A] (→JC) is revealed by the cautionary  before a in bar 7.

b. 19

composition: WN 17, Polonaise in B♭ major

..

In JC there is no  lowering a3 into a3, which is a patent error; in the copy there is also no relevant sign before a2. PE is also missing a flat before the latter, which can correspond to the notation of [A], as Chopin often extended the validity of cautionary accidentals onto entire passages or scales of this kind.

The same applies to bar 46, marked in the sources as a repetition of bar 19.

..

None of the sources has the  lowering a1 into a1. In JC and EF, in which the first two demisemiquaver groups in this bar are written with the use of an octave sign (overseen in JC); however, one cannot even talk about an inaccuracy here, as the  before the note of this pitch is already in the 2nd group of demisemiquavers.

b. 78-80

composition: WN 17, Polonaise in B♭ major

..

In the entire A major fragment, it is only EF that has a correct notation, as far as the accidentals are concerned (however, we add both signs in the 3rd triplet in bar 80 and the natural in the 5th triplet, required in accordance with the rules adopted by us). PE lacks some of the signs, which, however, does not have any impact on determining the correct text; similarly in JC, where there are only few necessary signs.
