Bianchi frameset ID/age?
 

I was given this Bianchi Frankenbike to replace a bike destroyed by a motorist. Any idea what year or model it is? The tubing is Columbus with Campagnolo dropouts. Brake bolts are not recessed. The chainstay & brake bridges are cast, and the lugs are pantographed. The frame is also fully chromed under the paint.

My guess is early 80s, but it's just an educated guess.
