The Modello 35A was one of the oldest guns used by the Italians in World War Two. It had no recoil system and ramps had to be used to re-set the gun after firing. The Italian army still had larger numbers of this gun in service at the start of the war and it saw action during the Spanish civil war. It was also used is action against the French, Greeks and Yugoslav armies in 1940-41 and many were issued to heavy gun batteries in North Africa and Sicily.
