In A (→FC→GE1, →FE→EE1) there is no accidental before the last crotchet in the R.H. It must be a mistake, cf., e.g. analogous b. 497. Oversight of an accidental necessary for writing a note belonging to a currently valid key is one of Chopin's most frequent mistakes. A natural was added only just in GE2 (→GE3) and EE2 (→EE3); it was also added in FESf.
