The third (e) of the seventh chord present in AsI having been replaced with a g fifth seems to be the composer's mistake rather than an intended change. It is indicated by:
- complete lack of the third of the chord on the 4th quaver in the bar in this version – performing the Variations solo,
- e present in a respective chord in both analogous b. 138 and 146,
- the presence of a third in the orchestral part, which, in this bar, is no different from both previous analogous places.
In this situation, in the main text we adopt the version of this chord written down in AsI, adding a 
to that note, undoubtedly overlooked by inadvertence in this draft manuscript.
See also the note in the next bar.
