Wartime Columbia. I think the Stars are a Columbia thing, that and there have been 3 other Columbia lightweight threads in the last week. Why stop now? I'd have to check but there were only a couple of companies that were allowed to continue producing bikes for civilians . As I recal, Monark was chosen for the military bikes but I forgot who got the civilian privileges.
Skiptooth coaster brake, Persons saddle, Torrington pedals, and you see that cute finned fender on a lot of american lightweights of that era too, including that new Pinup thread.
A good night for ladies on bikes.
