After the first two volumes on Italian artillery, devoted to the study and analysis of artillery pieces inherited from the First World War, both domestically produced and sources of wartime prey (typically Austro-Hungarian) following the victory in 1915-18; in this third and final part we will treat and complete our work on Italian artilleries of the first fifty years of the twentieth century, dealing mainly with the more modernly designed pieces conceived from the second half of the 1930s. The criterion used will still be that already used of the caliber to grow, so from light pieces onwards. At the end of the volume there will be the third part devoted to tractors and tractors, which in doing so will be distributed in various ways throughout the three volumes but always in chronological order.
