This may be a stretch on RRB, but is anyone aware of a semi-accurate way (other than the serial stamp) to identify the year of a Schwinn road frame just by looking it over? I'm interested in this Varsity (link below), which the seller estimates to be a '60 or '61 model, but believe that such a model would have the "jockey" or "suicide" derailleur common on Schwinns at the time. If this isn't as early a model as thought, how can a later year be deduced? Thanks!
