The Type 97 was a copy of the Czech ZB-26 machine gun which was used in early Japanese tanks and tankettes. It is chambered for 8mm Mauser, and uses standard ZB-26 20-round magazines. This particular one is in the collection of the owner at Battlefield Vegas, a machine gun rental range in Las Vegas. It is particularly cool because in addition to the gun, he has the mounting point cut out of a Type 35 tankette which fits the gun.
