One thing I have found is that the SR cranks on my bike bear a date from 1977. That seems to make the 1979 start date for Centurions mentioned in the followups unlikely, though it is possible that the previous owner replaced the original cranks with cranks from 1977.
You'll be able to get date codes off the freewheel and stem and possibly the levers/brakes. It's unlikely that all the components were changed out at the same time, so if they are within a year of each other, you have a good approximation of the age of the bicycle. As for the derailleurs, they are probably an upgrade. The originals were probably SunTour, like the shifters.
Given that the stays are chrome, it is likely a decent tubeset. Measure and post the seat post diameter, as it is a pretty good indicator of tubeset quality.
