Yes, as USAZorro says, ebay is the best place to do your research. Try to track similar bikes. Nuovo record components on a Superissimo may be a little hard to match but you should get a rough idea. Look for a bike of similar condition.
I understand, and I could be wrong, that the Superissimo's used Columbus SLX tubing which was different to the more commonly found Colnago Super's which were made more commonly with Columbus SL tubing. I think the Superissimo's were an 80's Colnago model range.
