After the first volume on Italian cannons, in this second part we will treat and complete the study and analysis of the artillery pieces inherited from the First World War, both of national production and sources of war prey (typically Austro-Hungarian) following the victory in 1915-18.The criterion used will still be that of the growing calibre, i.e. from light pieces onwards. With the third volume, which will complete our work on Italian artillery from the first fifty years of the twentieth century, we will mainly deal with the more modern types of artillery, conceived from the second half of the 1930s. From this volume we will also expressly discuss the bombards in use in those years, while tractors will be distributed in various ways throughout the three volumes in preferably chronological order.
