In the main text we include the cautionary 
to f3 in bar 28 (L.H.), added in GE (→FE,EE,IE). We also add a respective accidental to the R.H. (5th quaver). By contrast, we omit the poorly justified cautionary flats to a
2 at the end of bar 28 (L.H.) and on the 3rd quaver in bar 29 (R.H.) present in the sources.
