Development and Production History
The gun resulted from a modernization of the Russian 122-mm howitzer M1910, initially developed by Schneider Electric. The M1910 was employed by the Imperial Russian Army during World War I and remained in service after the revolution.
In late 1920s the RKKA decided to upgrade the M1910. The modernization, handled by Perm Plant in 1930, included:
- Lengthening of the chamber by one caliber
- New sights
- Strengthened carriage
- Strengthened elevation mechanism
- Minor upgrade of the recoil mechanism
The resulting gun was adopted as 122-mm howitzer M1910/30. The exact production statistics exist only for years 1937 to 1941 when the production stopped. During that period Perm Plant produced 3,395 pieces. In addition, 762 old M1910 guns were upgraded to the M1910/30 standard.
The M1910/30 was a typical short-barrel howitzer, intended mostly for shooting with elevations from +20° to +45°. Shell could be fired with six propellant loads (no. 1 to 5 and full), but when shooting with elevation smaller than +20° with full propellant load, the gun was prone to turning over. The gun had interrupted screw breechblock; hydraulic recoil buffer and hydropneumatic recuperator were both mounted under the barrel. The carriage was of single trail type with unsprung wooden wheels (from 1936 some guns received steel wheels with cast rubber tires) and limited traverse.

Famous quotes containing the words development, production and/or history:
“Such condition of suspended judgment indeed, in its more genial development and under felicitous culture, is but the expectation, the receptivity, of the faithful scholar, determined not to foreclose what is still a question—the “philosophic temper,” in short, for which a survival of query will be still the salt of truth, even in the most absolutely ascertained knowledge.”
—Walter Pater (1839–1894)
“[T]he asphaltum contains an exactly requisite amount of sulphides for production of rubber tires. This brown material also contains “ichthyol,” a medicinal preparation used externally, in Webster’s clarifying phrase, “as an alterant and discutient.””
—State of Utah, U.S. public relief program (1935-1943)
“In front of these sinister facts, the first lesson of history is the good of evil. Good is a good doctor, but Bad is sometimes a better.”
—Ralph Waldo Emerson (1803–1882)
