122 mm corps gun M1931/37 (A-19)
 
Soviet field gun produced from 1931-1946, combining the carriage of the ML20 with a slightly earlier 122mm field gun. The medium artillery piece was pressed into service in an anti-tank gun, though the carriage was not fully suited to this role. The gun was latter used to arm ISU-122 self-propelled gun, while a modified version was used on the IS-2 and IS-3 heavy tanks.

Used from Khalkhin Gol in 1939, it continued in Soviet service long after WWII. German, Romanian and Finnish forces used captured examples.

This kit can also be assembled as an ML-20 152mm gun.
