b. 107-108

composition: Op. 21, Concerto in F minor, Mvt I

..

In A (→GE1FEEE1EE2) there is neither a  returning ain bar 107 nor a cautionary  before ein bar 108. In GE2 only the first was added and in EE3 – only the second.
In analogous bars 105-106, Chopin wrote in A both signs, which suggests that at the time of writing a repeating phrase, the composer's concentration broke (cf. bar 107). It increases the likelihood of oversights of ties at the end of bar 108.

b. 108-109

b2 repeated in A (→GE)

btied in FE (→EE)

..

The tie of b2, added in the proofreading of FE (→EE), most probably by Chopin, is, according to us, a correction of the oversight of A (→GE) and not a change of the performance's concept. See the note on the L.H.

The missing tie of cis most probably Chopin's oversight – a corresponding tie is in analogous bars 106-107. See also the note on sustaining bin the R.H. as well as bars 107-108
