b. 5

composition: Op. 25 No 11, Etude in A minor

..

In EE1 there is no pedal release sign. The oversight – probably of the copyist performing the base text, as the sign is also absent in bar 69 – was corrected in EE2 (→EE3). Cf. one of the previous notes in this bar.

with bass in A (→FE,FCGE) & EE2

 under semiquaver in CXI

No markings in EE1 & CGS

..

The placement of the  mark in CXI is probably an inaccuracy. However, if the manuscript was indeed based on a lost authentic source, such a later pedal, resulting in the notes ringing out clearer further on in the bar, could have come from Chopin.
The oversight of the  mark is probably an inaccuracy of the copyist – there is a similar situation in bar 8.
The missing pedalling indications in CGS – see b. 3-4.
The oversight of the engraver of EE1 was rectified in EE2.
