Your basic American three-speed of the 70’s: Shimano 333 hub, one-piece crank, etc. Probably manufactured for Coast-To-Coast Stores by Huffy. The owner of this bike didn’t bother locking it for the one-minute excursion to the library. And really, who would steal it? Not that it’s in bad shape, or that it’s not a “real” bike, but it’s on the low end of the totem pole of desirability.
