b. 66
EEW does not contain the raising d2 to d2, which must be an oversight by the engraver. The corresponding accidental in FE was almost certainly added in the last stage of proofreading FE1, hence initially it was also absent in GE1, in which it was added in print along with a few other sharps. This can be deduced from the fact that both FE1 and GE1 did not provide space for this accidental before the note; therefore, in both editions it must have been added only just in the stage of proofreading the already printed text.
