It is truly a beautiful bicycle and based on its quality, it could certainly be considered a "classic", provided all the components are from the same era. I do not consider it to be "vintage", as I reserve this term to what is commonly refered to as "old school", such as non-index shifting, non-aero brake cable routing, toe clips and straps etc. A vintage bicycle is not necessarily premium quality, whereas a classic is.

I offer the following from my collection as examples. The first is my "classic" Mark Nobilette custom built frameset with index shifting, aero brake brake levers and clipless pedals. The second is my Ron Cooper frameset restoration in progress with Campy friction shifters, standard non-aero brake levers and quill cage pedals with toe clips and straps.
