152 mm siege gun M1910

152-mm siege gun model 1910 (152-мм осадная пушка образца 1910 года) was a heavy gun used by the Russian Army in World War I. The gun was developed by the French arms manufacturer Schneider and the first production bunch was built in France; later on the production continued in Russian Empire.

After World War I the gun saw combat in Russian Civil War. In 1930 and 1934 it was modernized, resulting in 152-mm gun M1910/30 and 152-mm gun M1910/34. Eventually the barrel of the modernized gun became a base for one of the most successful Soviet artillery pieces of World War II - the 152-mm howitzer-gun model 1937 (ML-20).
