Development and Production History
The gun resulted from a modernization of the 152 mm howitzer M1910. The M1910 was initially designed by Schneider. Putilov Plant and Perm Plant delivered 348 pieces in 1911-27. By 1936, the RKKA possessed 101 M1910s, including 5 practice pieces.
Work on modernizing the gun started in 1936. Because of small number of M1910s in service, extensive upgrade was not considered worthwhile. The gun was rechambered for larger cartridge, same as used by the 152 mm howitzer M1909/30; upgraded barrels received a mark "lengthened chamber". Some pieces also had their wooden wheels replaced by steel ones with rubber tires, resulting in much higher transportation speed of 18 km/h. The modernized weapon was officially adopted as 152 mm howitzer model 1910/37.
By 1941, all M1910 howitzers were upgraded. There was no production of new pieces.
The design of M1910/37 was typical for World War I era howitzer. The gun had short (12 calibers) barrel with eccentric interrupted screw breechblock; hydraulic recoil buffer and pneumatic recuperator were both mounted under the barrel. The carriage was of single trail type with limited traverse and, typically, unsprung wooden wheels (some pieces received metal wheels with solid rubber tires). The gun was typically towed by a horse team (eight horses) by means of a limber. For each gun three horse-drawn ammunition boxes were issued; each box held 22 projectiles and 24 propellant charges.

Famous quotes containing the words development, production and/or history:
“The proper aim of education is to promote significant learning. Significant learning entails development. Development means successively asking broader and deeper questions of the relationship between oneself and the world. This is as true for first graders as graduate students, for fledging artists as graying accountants.”
—Laurent A. Daloz (20th century)
“To expect to increase prices and then to maintain them at a higher level by means of a plan which must of necessity increase production while decreasing consumption is to fly in the face of an economic law as well established as any law of nature.”
—Calvin Coolidge (1872–1933)
“My good friends, this is the second time in our history that there has come back from Germany to Downing Street peace with honour. I believe it is peace for our time. We thank you from the bottom of our hearts. And now I recommend you to go home and sleep quietly in your beds.”
—Neville Chamberlain (1869–1940)
