The fingering of FEH, which is not written by Chopin's hand, yet it may come from a lesson with the composer, is based on a different idea than the fingering indicated by Chopin in FED. In the further part of bar 24, both fingerings are much more compliant. Fontana's fingering in EE significantly differs from the indications included in FED; in turn, the discrepancy with respect to FEH concerns only the 2nd and 3rd semiquavers in bar 23.
