ザ Fiat SPA CL 39 is a light truck designed for moving troops in the mountains. It was the successor to the OM 32-35-36-37 models, the so-called “motorised carts” of 1925 designed to replace horse-drawn carts. Developed on the model of mountain tractors, it was less rustic than the latter, faster and very easy to drive. It was launched in 1938 under the name CLF (Carro Leggero per Fanteria), originally with two different engines, one air-cooled, the other water-cooled. It was the latter that was chosen by the Regio Esercito (the King of Italy’s army), and presented at the Centro Studi Motorizzazione on 13 November 1938.
