There are 5 metal rivets evenly spaced around the lower third of the shell, with a hole on the right side for a missing 6th rivet. These rivets were attachment points for a cloth liner and chin strap that are missing from this helmet. There are traces of dark green paint just above the brim exterior.

Production of the Ssh40 model helmet began in 1940 and continued until 1960. It was issued to Soviet soldiers on all fronts during World War II. The Ssh40 was designed to replace the Ssh39, which had a liner that made it difficult for the wearer to place the helmet over a winter hat or garrison cap. The Ssh40 was designed to solve this problem by attaching the liner to the exterior shell near the rim, which allowed the helmet to slide over another hat. The Soviet Union occupied the independent state of Latvia in June 1940. It was later occupied by Nazi Germany in July 1941. In 1944, the Soviet army reentered Latvia, which became a Soviet republic."@en ;
