Regarding the later Paramount frame set ebay item # 120543784694
Is in reasonable shape, and an odd color. Its big paint blemish tire rub on the inside of the RH chainstay probably helps its claim of being in original paint. The color layers showing are in order of the Schwinn factory finish.
I vaguely remember this color as seen on the Scrambler bikes way back, but was not paying much attention, and do not know the marketing name of the color. It does show well.
As to the logic of ebay, I have no insight, perhaps chaos theory would help.
