Luckly I had the opportunity to recieve a lot of informations about this car, during the organization of the Florence exhibition (pics posted by dzima1985), when I've have written all the descriptions of the cars showed.
Unluckily I didn't recieve the informations directly from the present owner of the car but from someone else from the organization of the show, and I'm not sure about their reliability... but they are really accurate so I guess they are also good.
I post the description text in english:
The OSCA, acronym for Officine Specializzate Construzioni Automobili (Automotive Workshop Specialized Construction), is founded by the Maserati Brothers after the transfer of the House of trident to the Orsi family. After the brilliant successes of the competition models built in the '50s, at the beginning of 1960 starts the production of a GT coach meant also for the road, the 1600 GT. In 1963, the OSCA is sold to Count Domenico Agusta, who plans a complete renovation of the vehicle concept, creating an ultra modern car. This new car is presented at the Turin Motor salon in 1964 and is a futuristic coupe built on the 1600 TC frame, standing for “trave centrale” (“central beam”).
The frame is built by Gioachino Colombo and is dressed with a fiberglass body, built in a single piece by the body shop of the Corbetta Brothers of Milan, already collaborating with Agusta for the construction of helicopters. The design is by Franco Scaglione and the development is followed by engineer Michel Liprandi, expert in working with fiberglass.
The car travels thousands of miles in testing, but the project is stopped without the construction of another copy. The prototype is sold in 1967 at the liquidation of the company and remained hidden until now, shown for the first time since 1964.
