Yes, they are 220 volt 60 cycle fans.   From a 1924 catalog:The Cat. No. did not change over the years for basically the same fan.  Dating is done by the "Form Number or Form Letter".
Form AB is 1922  The blade should be brass and highly polished after 1919.

Below is a very original 1922 Form AB.  The medium green color photographs differently depending on the light.
These are some of the very best GE fans I think, are all cast iron motors and bases, and pretty easy to work on.   I can't give you any help on making your 220 volt fan easily usable on 110 volts other then using a step down transformer.
