The book American Excelsior contains a list of the annual production for the |
factory. Those numbers are fairly reliable since they come from the factory annual
reports for most years, at least during the Schwinn era. The numbers for Super Xs
were always low. As for the Ballak serial lists, The American Excelsior Supplement
contains a discussion of the lists and points out the strengths and problems with
the lists. The Ballak lists remain probably the best we have for serial ranges.
