I have a 1973 Schwinn Super Sport lightwieght frame 58cm. I would say that the bike has been and still is well taken care of. Tune ups etc. A few scratches in the paint but nothing too bad. Never been in a crash. No dents or cracks anywhere. I wanted to look into selling it, but I don't know what I should ask for it. I was told by the first owner that it was close to 600.00 new in 1973. Seems high but that's what I was told. It has the following all original parts:
Shimano 600 drive train.
Cinelli drop bar
