Welcome to the forums.
I like older Dura Ace, and your attractive bicycle has at least some of that for starters.
On a bike such as yours, I would get it to fit, make sure maintenance is up to par, and check for safety items.
I don't assume anything.
Are you a decent mechanic?
If not, I would suggest these two sites to get you up to speed:

If you are not comfortable doing the work or lack the tools, find a good mechanic at a shop or coop.
I have a couple of the top racing mechanics in the Midwest help me from time to time. Not because I am a top racer, rather they are incredible at their craft and I don't mind paying for excellence.
Worth your weight in gold. imho
....and don't forget to bring in a case of beer for the guys occasionally. It is amazing how fast my bicycles get turned around!
