The traces of erasing visible in A still allow us to decipher that initially the 4 bass notes in those bars had been A flat-A flat-A flat-A flat1. Eventually Chopin changed them in A to A flat1-A flat-A flat1-A flat. Cf. similar alterations of the same notes in the Polonaise in C sharp minor Op. 26 no. 1, bars 45 and 52-53. Cf. later overlapping changes in teaching copies.

Erasures visible in A over the R.H. part seem to confirm that Chopin removed the earlier markings, including staccato dots over each one of the sixths and two half-bar slurs.
