) in In A the 
mark is written before the bass E, which, due to the significant horizontal spaces between subsequent notes, does not contribute to misunderstandings – both in FC (→GE) and FE (→EE) it was placed under that note. In turn, in CGS a respective mark was placed not only before the note (like in A), but also before the bar line; moreover, the e1 crotchet in the upbeat falls precisely over that mark, which already changes the meaning of that indication. Such a pedalling would be perfectly acceptable; however, it is difficult to say whether the copyist conveyed here a pedalling variant, perhaps authentic, or whether she simply inaccurately wrote the version of FE. A mark at the beginning of the piece (written already under the time signature) appears also in CXI.
In CGS the discussed mark is the only pedalling indication in the entire piece. Therefore, it suggests another possible explanation for such a position – placed at the beginning of the piece, the mark is just a general indication, according to which the pedalling should be natural (=harmonic).
