Valtion Patruunatehdas WWII Dated Brass 4 Different Years

Valtion Patruunatehdas, Lapua, Finland.  It’s the same size casings in the Russian Mosin Nagant rifle, but according to the head stamps this brass was made in Finland!  Anyway, very cool WWII casing collection for sure.  There are four dates in this set, 1939, 1940, 1942, and 1943.
