The parts group indicates that it is a later version, although the olympic victory stuff came from the mid '80's. Treviso is where it was built. The actual model should appear in text on the top tube near the handlebars, although this almost always goes missing. marca dep. is the rough equivalent of trademarked, I think. The RSX is probably an upgrade to get 7 speed brakes/shifters onto an older ultegra group, would be my guess.

The value depends heavily on the condition of the frame and finish, and on the condition of the parts. Columbus SL frames in good condition will fetch $2-300 on ebay. The parts group that is on it is not particularly coveted, so it may be worth another $100. If the bike is near perfect, it will bring more. If it is thrashed, well, not so much. Dents? Scrapes? Forks bent? Big dollars off.

Pinarellos are really nice bikes - hope you can save this one. Post pics for a better guess at the value.
