Well, thanks to the help of a few CR listers, it appears that I have a Serotta Club Special from pre-1982 (the year they started using Cinelli bottom brackets, which mine does not have).
So here's my next request (yes, I'm an ingrate):
Does anyone have pics of a pre-1982 Club Special? I'd like to know what paint schemes were offered, how they were built up, etc. You can send them to me at dgranger@comcast.net.
