Rarely seen in American collections, this is a scarce Japanese military training machine gun. Developed around the same mindset as other low-powered "school" weapons intended to introduce Japanese students to the fundamentals of military drill, this is a simplified, open bolt, straight blowback weapon intended for use with lower powered drill ammunition. Using a lighter charge and a simpler mechanism, these training machine guns were less expensive and easier to make than their service-grade counterparts, while still providing an experience that would translate to the real thing. Fitted with a left offset blade front sight and a similarly positioned peep rear sight, with a heavily finned barrel, a faux gas tube/bayonet mount, fixed carrying handle, and a smooth pistol grip and buttstock. A bipod set is installed on the barrel swivel, with an "anchor" mark on top of the receiver and a boxed set of school-style markings on the left side of the buttstock. Magazine absent.
