2526 (2522, 2523, 2530) - The other factory special built exclusively for the 1956 race at Monza. It had the angled engine (fuoricentro), lowered seating position, revised bodywork and fuel tank. It was only raced by the factory twice and then retained by the works team until 1958. In 1958, it was re-numbered as 2530 and sold to Antonio Creus since '2526' had already been applied to 2522 or 2523/1 when it was sold to Keith Campbell. It was initially thought that Campbell had been sold 2501, but that was due in part to the new bodywork which was very similar to that of 2501.
