In GC (→GE1), FE and EE1, before the last octave in the R.H. (c
3-c4) there are flats. The signs, completely unjustified in this place, must have been also in [A], which is a very meaningful example of Chopin's uncertainty concerning the issue of the prevailing set of key signatures, particularly the last one. The signs were removed in GE2 (→GE3) and EE2, while in GE3 they were reintroduced, which indicates rather a mechanical work of the reviser of EE3, copying the versions of GE1 without having analysed their accuracy.
