It is unclear how the difference in the way of indicating crescendo in bars 127-128 occurred. The 
sign could have been added by Chopin in GC, however, according to us, it can be considered an addition (enhancement) to the verbal indication. In the Chopinesque notation, a verbal indication generally indicates a global dynamic increase, generally related to a progressive harmonic sequence and often including a few bars, whereas the hairpin generally concerns shading of the melodic line. Therefore, we also suggest a solution combining both versions of the indications, in which cresc. - - - in bars 127-128 is continued next to the hairpin, probably in accordance with the performance intended by Chopin – see also bars 135-136.
The total absence of dynamic indications in GE1 is a patent error, corrected in GE2.
