Unimodel Military 1/72 M12 155mm US King Kong Gun Motor Carriage Kit

The 155 mm Gun Motor Carriage M12 was a U.S. self-propelled gun developed during the Second World War. It mounted a 155 mm gun derived from the French "155 mm GPF" gun.It had an armored driver's compartment, but the gun crew were located in an open topped area at the back of the vehicle. It mounted a 155 mm gun M1917, M1917A1 or M1918 M1, depending upon availability, a weapon derived from the nearly identical French 155 mm GPF gun of World War I vintage. Limited storage space meant that only 10 projectiles and propellant charges could be carried on the vehicle.
 

An earth spade (similar to a bulldozer blade) at the rear was employed to absorb recoil. This layout—large gun mounted in an open mount at the rear, with a spade—was the pattern adopted for many years by other heavy self-propelled artillery.Given the limited ammunition carried in the M12, a support vehicle based on the same chassis was produced as the Cargo Carrier M30. It was designed to transport the gun crew and additional ammunition.
