There seems to be a lot of vintage Colnago Saronni frames on the market and the link here is to a an eBay listing for one such frame;

As a group of vintage enthusiasts can we spot the difference(s) between one of Ernesto Colnago's rare gems and a fake? It might be that this is a real example and not a fake.
