A has an additional note, E
, in the last crotchet in the L.H. It is almost certainly a mistake of the person writing certain fragments of Tutti in bold (see the characterization of A). Interestingly, the note is absent in the editions, although there are no traces of it having been deleted in GE1. It could mean that at the time when A served as base text for GE1, the fragments in bold type and the mistake were absent (it is not a conclusive argument, since the engraver could have simply confused the bars, printing the octave from bar 53).
