A (→GC,FE1→FE2) lacks naturals before b in the L.H. and b2 in the R.H., while 
before b1 is written only on the 8th semiquaver (instead of the second). Those obvious imprecisions were corrected in other editions: in GE & EE all three necessary naturals were added (the on the 8th semiquaver, superfluous after those corrections was only removed in EE), and in FE3 only the signs before b and b2.
