The Ford GPA was a unique vehicle which was deployed not only on the U.S. side by the Army and Marine Corps, but also later by Russian forces. It was often called a "seep" (an abbreviation of "seagoing jeep") on account of its amphibious nature. The front-engine 4WD vehicle shared much of its design and parts (including the engine) with Ford's GPW. Around 12,800 units were produced by 1943. This kit includes a variety of new parts to update Item 35043 U.S. Amphibian Ford GPA Kit.
