This frame was made in a small workshop by artisan Paolo Bassan from Padua. He made a lot of very good frames with his own brand name. My friend Marzio from Gorizia-Italy known him and he told me that he was many times in his workshop. There was always a lot of his friends playing cards, drinking a glass of wine or just talking about daily news. He was a very good frame builder. Here is a frame made by him in 80s with Columbus SL tubes.
