The puzzle car is the final version of the Moretti Cita 350, which was reworked by Cita designer Count Mario Revelli de Beaumont with a tidied up front grille, which was only fitted to the final Cita 350 cars made, in 1949. The engine was still the 350 cc vertical twin-cylinder motor with an aluminium crankcase and nitrided cast-iron sleeves mated to a 4-speed gearbox.
