In A Chopin overlooked a few necessary flats in the R.H. part: in b. 19 d2, in b. 21 d3 and g2, in b. 22 d2 and d3. FC added only the first  in b. 21; in addition, the copyist overlooked the  of g2 in b. 23. FE also added only some of the necessary flats, next to d2(3) in b. 21-22, and – which is puzzling – also overlooked the  of g2 in b. 23. GE and EE added all necessary accidentals.
