When WW2 ended, few finnish scouts stashed weapons in the fear of a new war. If a new war would've been started, they had the weapons to start guerrilla war against the invader. When the Soviet Union collapsed, they dug out the weapons. Here Olavi Paukkunen, who served as a scout, is showing two M/31-submachineguns, also called "Suomi-kp"(Finland-smg)

This is the Japanese Tachikawa KI-55, codenamed Ida by the allies. There are only 3 examples left in the world and this is the only remaining trainer version. It resides in the Royal Thai Airforce Museum in Bangkok. The Thai airforce purchased 24 from Japan in 1942. The combat version (KI-36) were mainly used in China as they were no match for allied fighter planes, some were later used as Kamikaze planes.
