My schwinn varsity is what I believe to be a 60's model but I'm not sure how to tell. It is all original except for the bar tape (the original was gone when I got it) which I replaced with green cloth tape which looks very good. I fine tuned it so that it shifts with just a tap of the lever. I was having trouble with the rear brake because whenever I adjusted it a day later it would be completely loose again. It turned out that the cable was frayed inside the housing so the spring was not bouncing back. I'll post pics as soon as I can figure out how to get my camera working. :)
