In excellent condition, all matching including the Dust Cover, we have an early intial series production Toyo Kogyo manufactured 30th Series Japanese Type 99 Service Rifle. The maker Toyo Kogyo, of Hiroshima Prefecture was a subsidiary of the Kokura Arsenal and they are not as common as the Kokura and Nagoya made rifles.  The factory was destroyed in the first Atomic Bomb attack.  This is an early production rifle that is totally matching and has all of the early production features such as the monopod and anti-aircraft rear sight.
This rifle was said to have been brought back as a War Trophy from Tarawa with the battle flag and bayonet as shown. The sling is still attached but it is broken.
The Type 99 was the standard 7.7 m/m Japanese rifle of the Pacific War.  Although it never fully replaced the 6.5 m/m Type 38 rifle In the Japanese Army it was the most commonly encountered rifle outside of the the China Theater.  This is exactly what you are looking for if you want a main line Japanese Army battle rifle.  Of course you never have to worry about a bad bore on one of these rifles as the bore was chrome plated.  The Type 99 rifle was a very innovative design for a bolt action rifle, and while it may have been a dated and obsolete design by the standard of the semi auto rifles such as the Garand, it was very well suited for tropical service in harsh jungle conditions and it was a prized war trophy.
