The World Famous Jeep produced by Kaiser Willys and Ford for WW II.
One of the first military vehicles mass-produced in the United States, the Willys MB (and
Ford GPW) US Army jeep is the culmination of war-time ingenuity, standardization and
strategic personalization for transport of personnel and cargo. Soon to become the
universal, "world-famous" jeep, the Willys MB and Ford GPW models were very effective
on the ground, with many standardized features such as 6.00x16 tires, 60 horsepower at
4,000 rpm, a gasoline can bracket on the left rear, provisions for trailer lights, a blackout
light system and sealed spring shackles. Production Total: 361,339 (Nov. 18, 1941 to
Sept. 21, 1945).
Prior to the production of the MB/GPW, other attempts were made to satisfy the Army's
need for a light utility vehicle including specifications that the vehicle have: four-wheel
drive, a crew of three on a wheelbase of no more than 75 inches and tracks no more
than 47 inches, a fold-down windshield, a 660 lb payload, and an engine capable of 85 ft lb.
of torque, along with an empty weight of no more than 1,300 lbs.
Another company, American Bantam Car Company, presented the first prototype which
met the Army's Specs, however, lacked the ability to mass produce the large Quantity that
was intended for this Army vehicle. Therefore, the Production Contracts went to Willys
and Ford after they proved to meet the Army's Specification.

It appears the back of this Jeep is a Machine Shop, vintage 1940s,
because that looks like a metal Lathe on the Jeep.
Do not try this at Home.
Looks like a Howitzer was fired while attached to a Jeep and
the Re-coil lifted the Jeep up in the Air!
