Yeah, I should have known better looking at it, but I have never seen a headbadge date 6 years prior to the actual production? Did they just stamp a million of them when they started the run or something? It's stamped 3487. It defintely is an 83, too many braze ons to be a 78. It's never been rebuilt or repainted, it's too clean. The 77 badges weren't the round black and red, that listed the model name. Or were they? Maybe a miss stamped batch of badges that day?,,,,BD

I'm a little foggy on Schwinn roadbikes between 1980 to about 85.....
