In the 2nd half of the bar the bottom notes of the chords in the R.H. – these which require ledger lines in the notation in the treble clef – in all sources, except for EE, is placed on the bottom stave. The b
note in the middle chord does not require an accidental, although a cautionary 
is undoubtedly indicated here (it was added in GE2). In EE the notes were moved to the top stave (same as in our transcriptions), however, the which was necessary in this situation was not added. As a result, EE has here an undoubtedly erroneous chord with a b instead of b.
The cautionary flats before e1 and d1 were added by us.
