  b. 20

e1-b1 in CLI & Ap

b& 2 in FEcor

b1 in FE (→GE,EE)

The version of CLI and Ap is certainly earlier. Chopin must have deleted e1 already in the base text for FE. The fact that it cannot be a mistake is proved by the fingering digit (2) written under b1 in FEcor (overlooked in finished FE and the remaining editions). Cf. bars 22 and 24
