There is a guy named Daniel with Bianchi USA that I asked. He had me send a picture and verified the year and model of each. He would not offer info on how he identified them, but I think he is right on with what other info I have found across the world on the internet and talking to people. There are actually a lot of Bianchi threads on this forum that were helpful to me in buying what I bought. I just needed written verification from a reliable source. To me Bianchi would be a good source. I posted a few pictures from the ebay sale and one of the pics Rod posted in the thread here in my albums in my profile. Once I get the bikes I will take before, during and after pictures. I don't plan on touching the paint but would have no problem replacing components or parts with NOS or good used items. I also plan on riding them so a modern seat and clipless pedals will go on both if they will fit.
