The version with e3 present in FE1 (→FE2→EE1) (in both FE without the necessary in this situation) is almost certainly erroneous. It is proved by: c3 written in GC (→GE) and the Chopinesque corrections in FESch and FE3 (→FE4). The correct version with c3 is written inaccurately in some of the sources – the necessary is only in GE and EE2. Further omissions of accidentals – see the adjacent note.
