After he failed to win US military adoption of his toggle-locked rifle design, John Pedersen went looking for other countries that might be interested in the gun. One of these was Japan, which experimented with toggle-locked Pedersen rifles and carbines for several years in the early/mid 1930s. This particular one is serial number 8, and has a scope mounting rail attached to it. It functions like a normal Pedersen rifle, but has a rotary magazine instead of the en bloc clip used in the US trial and British-produced rifles.
