I joined the Centurion club yesterday with my purchase of a worn-but-functionally-sound Pro Tour. SN#M8B01507. There are photos in the "C&V-What's it Worth?" forum for the curious. So if you're still seeking serial number data, there you go. I guess this'd be a '78, yes? Whatever it is, I finally understand the difference between the low-mid bikes I've been riding and "the real deal." This bike is great, and I haven't even started tuning stuff up yet.
