When we visited the old office of DeRosa along the road to Brianza to use a pump in 1983, I was surprised to find no production facilities. Then I knew it had new workshop near the old office.
    I don't know exactly what " carrousel " means but I found a production line like a horseshoe when I visited there to order a frame in 1983. There were several young men including at least one son of Ugo but were not working then. So I cannot say whether the long stand like horseshoe was a automatic conveyer or not. The Casati at Monza made a large workshop comparable to DeRosa in 1983 but I did not find that horseshoe line but a vacant space.
    I heard that in early 1970s when Mr. Nagasawa, who later made the frames of Nakano, was at De Rosa, there were only Ugo, his wife and Nagasawa .
    And I was surprised to see a magazine of 1998 and to find the factory of DeRosa was much bigger than that I visited. Also surprised to find a palace of Colnago , big factory of Rossin ........
