I got this bike last night and was trying to date it and ran into a few things that threw me off. The serial number (which is located on the headtube, below the headbadge) is CJ87171 which made me think that it was from March of '73. The only problem is that the headbadge wouldn't match that I don't believe. Let me know what you think. took it all the way apart last night and everything, even down the the ball bearings in the 1 piece crank had Schwinn stamped on them.
