In June 1940 the US Quarter-master Corps published requirements for a compact 4x4, quarter-ton truck. Thus the GPW was born and the name shortened to ?Jeep?. Comfort was bottom of the heap of design priorities and all fours seats, and the ride, were hard. But the hastily conceived design was inherently right and over 600,000 were made up to 1945 with endless variations. After the war Willys plugged on with the Jeep in civvy CJ-2A form providing cheap, practical transport in austere times. This is a book of contemporary road tests, technical data, model introductions, military details, camouflage painting, operating details, history.
