Having been in the industry at about the time your frame was sold, and having been a dealer myself, it looks like you have a bike built up with a "take off" kit. Nothing wrong with that at all, it's how a lot of bikes were built up. Your setup was a favorite of ours - good frame with Ultegra (off, say, a Cannondale, but with Italian BB substituted in) with the Look pedals (which actually came with the Cdale bikes). The post and stem were the right sizes so things just popped into place. Debernardi's distributor didn't readily sell Shimano (they import Campy, 3ttt, some other Italian stuff - the guy who owns it is from "the Old Country") so to do Shimano we'd have to either buy parts from a different distributor or strip a bike. Your bike looks in very good condition and should last you a long time.
