Wore out three sets of tires already!
This is a 28 spoke 1960's Bendix Red band 2 speed kickback hub that would have been one of the hubs that came standard on a vintage Schwinn Stingray S2 wheel. I believe the most effective way to test if the index spring is working while unmounted is to rotate the hub to see if the gear teeth stay aligned with the spoke holes, and then in the other gear to see if they rotate faster than the spoke holes and this passes the test perfectly. I have never had it mounted since this is how I received it so I do not guarantee its operation after installation since I simply don't know. It is in very clean visual condition with no dings or dents other than the chrome not being a shiny as it probably was 60 years ago.
