According to us, the 1st finger given in FE next to the d1 note indicates a simultaneous performance of the d1-f1 third with that finger. The same is suggested by the fingering added by Fontana in EE. No fingering in GE may indicate that Chopin added the digit in FE in the last phase of proofreading. There is a similar situation in analogous bar 57.
