1(2) in The FE1 version featuring c
1 and c2 is probably authentic – it was introduced at the stage of proofreading (it can be seen that the 
to the last quaver in bar 180 was added in print), which rules out a mistake when copying or engraving. According to us, it is possible that we are dealing with an error committed while proofreading, resulting from the similarity between the ending of bar 180 and 181 and the ending of bar 184 and 185, which in FE are – as in our transcriptions – on adjacent lines, one above the other (the similarity is all the grater as in A (→[FC]→FE1) there is no lowering g1 to g1 in bar 185). Anyways, in FE2 the flats added by FE1 were changed to naturals, hence either returning to the original A version or correcting the previous mistake.
