Update - I did buy it for a little more than my offer. Based on what was on the bike I'm guessing maybe the Rossin might be authentic. I will have to do some sleuthing to find out. Miche, Modolo, Campy NR rear mech. Campy (??) front derailleur and shifters. SR post. Ambrosio 19 elite clinchers. Some minor surface rust on frame but is cleaning up nicely. Value knowing parts? Also came home with a 62cm Steve Bauer Chinook as a throw in.
