I agree with Bruce. I don't know of a Superior without a threaded BB.
I think this model name went back to the 1890s and was Schwinns top lightweight until the Paramount and then represent the second US built line in many incarnations. It seemed to come and go in the model line. The Schwinn World or New World would be the model with an Ashtabula crank In the early 50's, even the Continental had a threaded BB.
My wife has a Superior from about 1975. For some reason they changed the Sport Tourer name to Superior for those last few years.
