Although i connect the eighties with microfusione lugs and hence less elaborate handicraft, a San Rensho and/or Zunow from the early 80ies, with a full DA Aero group i would offer a warm spot in my Garage.
Any early 70ies team bike, Bianchi, Colnago, Gios, Gazelle, Benotto, Peugeot, i wouldn't mind owning. Also a Singer or Herse, though i'd prefer an older vintage of these.
Same for Bianchi Specialissima, Breschi Stucchi, Maino, Dei, Legnano.. these had to be 50ies or earlier
