Possible interpretation of AI

AI (probable interpretation) & A (→FEGE,EE)

..

In both bars in AI the semiquaver groups are written as quavers. It is a patent inaccuracy, following from the draft nature of the notation. The a1-a2 quaver in the 2nd half of bar 63 may be considered as totally deleted, which leads to an identical version with the remaining sources. However, it is also possible to consider it as a slashed grace note in which the bottom awas deleted.
