Similar lugs to the olympic master I just tuned. Not top of the line but I know little about late 80s, early 90s colnagos. The collector appeal is minimal as this really replicates the lug work of yesteryear (i.e. the colnago logos are cast into the lugs not hand cut). I would say $400 is a reasonable price to expect for the frame, only because it's a colnago. Most of us on this forum would not pay that much however. Your market is someone who wants to ride it, not a collector. Try your local craigslist before resorting to ebay. SOmeone should jump on it pretty quick just because of the name.
