  b. 37

e-e1 in GC (→GE) & FE1 (→FE2EE)

f-f1 in FE3 (→FE4FE5)

The version with e-e1 may be Chopin's mistake, who in [A] introduced the naturals raising it to e-e1 four quavers too late. In any case, Chopin proofreading of FE3 undoubtedly determines both the sound of this quaver and its enharmonic notation.
