Rare and interesting Italian headdress of the great war, it is a mod 909 belonged to an officer with the rank of lieutenant of artillery 1 RGT costa.Con the Order of 14 December 1914, the specialty artillery coast included: three artillery regiments from coast and two artillery regiments from coast and fortitude, which were distinct from the five regiments of fortress artillery. Upon mobilization for World War these regiments formed new departments militia Mobile and territorial militia. Early in the war the artillery from coast did not undergo changes: the strongholds maritime retained their armament; but when the political and military situation allowed the disarmament of some works, the artillery material was partly transformed and used in field operations. During the war the materials from coast artillery were more modern: the cannons 381/40 and 305/50, 305/17 and the howitzer cannon 152/50. This artillery, data gauges, began to be called "heavy" - term officially entered the Ordering in the twenties. Until the advent of tractors for towing mechanical (FIAT and Pavesi Tolotti) practically heavy artillery could not be moved, except using (in special cases) large towing with a significant number of quadrupedi.Nella World War set heavy artillery formed the "park of siege", comprising: cannons 149A, 210 howitzers, mortars 210, 149G cannons, howitzers 280A and 280G removed from coastal squares. In May 1916 the batteries of siege were 475 and grew to become 750 on the eve of the withdrawal of October 1917 (Battle of Caporetto) and became 890 in October 1918, for a total of about 3,700 guns of various calibers. The more "modern" installations of heavy artillery were: the mortars 260 and 210 on a carriage deformation and howitzers 305/17 and 280. Remember that the Ansaldo of Genoa had studied a "cannonissimo" 200 / 100 that was supposed to reach a range of 140 km. The project was not realized by the end of hostilities. After the Great War he returned to the clear separation of the two specialties of artillery and coast artillery fort. Returning to cap looks a little worn but all mounted at the origin and with beautiful patina of time the rest of the one hundred years there are all !!!
