Is it this bike http://www.mookietwoh.com/
I think it's at least possible that Cambio Corsa/Paris Roubaix equipped De Rosas could exist.
Ugo would have been 18 years old when the Gran Sport arrived on the scene in 1952. But he was already building bicycles by then, and in his own name. The history page on the De Rosa site says "In the early fifties Ugo De Rosa opened his first shop and dedicated himself to the manufacture of racing bicycles."
But, maybe he preferred Simplex ;^)
