If you zoom way in on that picture linked above it looks as if the dropout is stamped with something on both the top and the bottom. The problem is that its so blurry its pretty hard to tell if it is actually something stamped or some weird reflections from something off camera. Other then that it looks pretty spot on. And if you look up the 86' there is no white feathered outline around Colnago like the 88'.


EDIT: Just found this picture, the person says its an 88' but that is pretty dang spot on to the ebay sale.
