Obice da 210/22

The Obice da 210/22 modello 35 was an Italian heavy howitzer designed by the Italian Arms and Munitions Technical Service (STAM) and accepted into service by the Royal Italian Army in 1938. A total of 346 were ordered and the gun was produced by Ansaldo at their Pozzuoli factory. However production was slow and approximately 85 were produced by September 1943. After Italy surrendered Germany seized as many as they could and a factory in Northern Italy continued to produce a small number for the German Army. The carriage was split trail with four wheels which raised from the ground for firing and the gun was trunnioned under the breech to allow for maximum recoil and elevation.
