1/72 SR-I I-Go amphibious tank

In late 1934 Ishikawajima was charged by the Army with development of a new amphibious tank. This follows on only a year after they had made an amphibious version of the Type92 Heavy Armored Vehicle that tested well but was not selected for production.  Weight for the new armored car was set at 7 tons with two machine guns and a maximum armor of 10mm after Mitsubishi had tried their own much lighter amphibious armored vehicle (the SR I-Go) carrying one machine gun – and did not impress the Army with it despite some interesting innovations including propulsion entirely through movement of the tank’s tracks (no propeller).
