In AsIAf and A (→GE1EE1EE2) there is no  lowering c2 to c2. Chopin's patent oversight was corrected by FE1, GE2 (→GE3,FESB) and EE3.

b. 277

composition: Op. 2, Variations, complete

Neither AsI nor A (→GEFE1,EE,FESB) include an accidental to the 7th semiquaver. The F major chord underlying this place is, however, thanks to the C7 chords present directly both before and after it, temporarily the tonic, which requires the use of e2, and not e2. This conclusion is also supported by bar 285 – in the orchestral version of this phrase all sources contain e2(3). The mistake, patent in this context, was, however, corrected only in the stage of proofreading FE2, probably at Chopin's request.

b. 329-330

composition: Op. 2, Variations, complete

..

As in many similar situations, in A the majority of the necessary accidentals are missing – Chopin wrote accidentals only to the 2nd quaver in bar 329 (e2-e3-g3-e4) and the next semiquaver (b3), the penultimate semiquaver in bar 329 (b1), the bottom note of the 2nd triplet in bar 330 (g) and the bottom note of the 6th triplet in bar 330 (d1). Assuming that the accidentals of the first two-quaver figure of the passage are also valid in the second one, all necessary accidentals were already added in GE1 (FE,EE,GE2FESB,GE3). In FE a  to e2 on the 4th L.H. quaver in bar 329 was also added.
