continuing with the finnish smallarms:
KP/44 was the Finnish version of the Soviet PPs43 submachine gun that entered the finnish front around 1943. After capturing the weapon, our army imediately got intressed of its massproduction design and decided to copy it into 9,00mm Parabellum round and fit into production. After some byrocratic quarrels the weapons entered into limited scale production around the Soviet 1944 summer offensive, but not many were build before the truce and peace. Since the weapon manufacturing weren't allowed to continue by the Allied command, only around 10,000 examples were ever made.
Peculiarly, as the company (Tikkakoski) ordered to product the weapon was german owned, and once after the truce all german property in finland became Soviet property, one of the german engineers who then fled to Franco's spain took the blue-prints of this weapon with him and the weapon was later manufactured in Spain under the name DUX for some time.
