In these bars Chopin would consistently put accidentals in A (→FE) only next to the bottom notes of the L.H. octaves (or not at all, as is the case with the 2nd crotchet in b. 27-28). Moreover, in b. 32 the 
lowering c
1 to c1 was crossed out in A! In FC Fontana added only 4 naturals concerning c1, while GE and EE contain all necessary accidentals.
