Schwinn Superior Cranks - 1940s Era Find of the Week

I recently picked up a "relic" condition set of Schwinn cranks from a 1940s Superior bike. These are a three-piece crank set with "AS&Co" chainring. The set even came with the complete cotter pins. The cosmetic condition is pretty well-worn, but they should be perfectly workable on an old Schwinn 3-speed type bike from the 1940s.
