Well, I'm interested enough to see pictures. I know that for the 1978 model year Schwinn built up a number of fillet-brazed frames that had been made a few years earlier and sold them as Superiors, but I don't believe they were Super Sport frames since the BB shells were for three piece cotterless cranks instead of Ashtabulas. One of the colors was Flamboyant Red.
What's the serial number?
