It's cool to see a major firearms manufacturer highlight their SMG production in marketing materials, even in an email:



1926
TIKKA SUOMI SUBMACHINE GUN M31
The Suomi submachine gun was designed by Aimo Lahti in 1924. The gun was manufactured by Konepistooli Osakeyhtiö, which was established by Lahti, lieutenant Y. Koskinen, captain V. Korpela and lieutenant L. Boyer-Spoof, and which sold the manufacturing rights to the Tikkakoski gun factory in the early 1930s. About 81,000 units of the weapon were manufactured in the Tikkakoski gun factory between the years 1931 and 1945. In addition to that, licenced manufacturing took place in Sweden, Denmark and Switzerland for the army of the respective country.
