One thing that hasn't been mentioned is that all of the components (from levers to shoes) of and for the original Schwinn Expander brakes, both front and rear were still available and still cataloged in 1962. The point is that just because a bike has an expander brake mounted on it doesn't mean that the brake is original to the bike. Here at The CABE, we see many examples of drum brakes being bought on EBAY, DOND, or the For Sale section that are added to bikes just to make the bike more "desirable." Yes, drum brakes could be found on original Phantom bikes but just because they are there now doesn't make them original. The only way to learn about Schwinn bikes and to begin to understand the thousands of variations and idiosyncrasies is to start buying bikes, taking them apart, and figuring them out. Perhaps the OP needs to step up to the plate. As you know, Gary, it's independent research, years of experience, and a genuine interest in the hobby that are the keys to the ranch. It takes time, a serious investment in the bikes themselves, the willingness to take a risk, and the desire to further the hobby we love, not asking somebody else about how to tell if a spoke is authentic or not. In short, you've got to pay your dues.
