Starting from a3, the sources are devoid of flats. In Chopin's time, there were no strict rules concerning the scope of accidentals under an octave sign (or they were not strictly observed), hence accidentals were often omitted in similar situations. Wherever the text is obvious, as, e.g. in this case, we add respective accidentals in content transcriptions and in the main text.

The missing  in the sources could be an oversight, although such isolated  marks can often be found in Chopin's pieces, especially at the end, but not exclusively. In the main text we suggest adding [] to keep the performer from an earlier pedal release, which could be contrary to Chopin's intention, considering the crescendo.

composition: Op. 12, Variations in B♭ major

..

The natural raising b3 to b3, omitted in FE (→GE) – cf. the end of bar 212 – was added in EE. The patent mistake (by the engraver or by Chopin) is proven by the cautionary  to b3 at the beginning of the next bar.
