I have a low end Centurion, a Super Tour, that looks by the date on the crank and the deraillers to be a late 80's model. It has a different headbadge though. Someone suggested that I should post it here. I'm including the specs. here with some pictures and I will post the serial number later tonight or in the morning. Cheers.
