b. 148
In the majority of the sources, the raising d2 to d2 is not before the note but 7 notes earlier, before d3 written at the same pitch, which in that time was generally considered to be enough. Strictly speaking, the sign is not necessary there at all, since d3 written at the pitch of d2 is already on the 4th note of the roulade – this observation most probably made the reviser of GE2 remove the sign before the second d3.
