Could this actually be a Sprint model?
Paint looks very nice, so nice it makes me wonder if its a re-spray
Group is a lower level Campy and from the mid 90's ( i hate to call anything Campy "lower level" as most of it is still very good stuff though)- so obviously not Original install on the frame
Without any other info, id take an educated guess that its a 650-700$ bike at most, but others with more knowledge may contradict me
