The sharp in front of f
2 in bar 6 is present only in EE, while the 
in front of a3 in bar 7 appears only in the later impressions and editions (EE4 and all GE,s except for GE1). Moreover, in CLI there is no in front of f1 in bar 6. Those discrepancies does not influence the reading of the text, yet they result from the gradually specified rules governing the accidentals.
