152 mm howitzer-gun M1937 (ML-20)
 
Soviet heavy artillery piece produced from 1937-1946. Efficient in both a indirect howitzer role targeting infantry and fortifications, and as a direct fire gun against armoured targets. It was also used to arm the SU-152 and ISU 152 self-propelled guns.

First used Khalkhin Gol, and against the Mannerheim Line during the Winter War, it continued in Soviet service long after WWII. German and Finnish forces used captured examples.

This kit can also be assembled as an A-19 122mm gun.
