on casual inspection, as it was pretty much confined to the part of
the shaft INSIDE the bearings.

pretty good steel, I've seldom (if ever?) seen any rust there. Bent
shaft, dented end bells (different name?) as others have mentioned,
would also be serious. But I just took it that they were new/used,
and might actually be OK (hope so!).
