History
The configuration of the air defense gun M1931 owed much to the design of the contemporary Vickers 3-inch anti-aircraft guns. The Soviet M1931 like the Vickers gun had a two-wheeled carriage with collapsible cruciform outriggers.[1]
The M1931 was replaced in production in 1938 by the 76 mm air defense gun M1938 which had a four-wheeled dual-axle carriage with two collapsible outriggers. The M1931 and M1938 had nearly identical performance and were gradually replaced by the more powerful 85 mm air defense gun M1939.[1]
A number of M1931 guns were captured by Finland during the Winter War and were employed by them as the 76 ItK/31 ss during World War II.[3] Likewise, M1931 guns captured by the Germans were given the designation 7.62 cm Flak M.31(r) and used until they were either worn out or their ammunition supply ran out. A few were rebored to fire German 8.8 cm ammunition and redesignated the 7.62/8.8 cm Flak M.31(r). However, the majority were scrapped in 1944.[1]
After the war, a number of Finnish guns were converted into light coastal guns (76 ItK 31 Rt, where "Rt" stands for "rannikkotykistö" = coastal artillery) by the addition of a scope site with manual lead mechanism for direct fire against moving surface targets. These guns were still in use as training guns of the coastal artillery into the 1980s.[4]
