CCKW 2 1/2 Ton 6x6 Cargo Truck
Although many vehicles were in use in World War II, it was the 2 1/2 ton 6x6 (the "deuce and a half" or just "deuce") that made an outstanding contribution. After the war, the Allies' superior ability to move mountains of supplies was recognized as one of the keys to victory. No vehicle was more important in that superiority than the GMC CCKW 2 1/2 Ton 6x6 Cargo Truck, the "Jimmy." General Motors Corporation (GMC) produced the CCKW from 1941 to 1945, with 562,750 manufactured. It remained officially in service with the US Army until 1956 and did not really disappear for a decade or more after that.

The GMC CCKW 2 1/2 Ton 6x6 Cargo Truck was produced in two chassis lengths:
- CCKW-352 Short Wheel Base, 145 inches
- CCKW-353 Long Wheel Base, 164 inches
The CCKW-352 was intended as an artillery prime mover while the LWB CCKW-353 was for general cargo and troop transport. In addition to the common cargo body, many other varieties were produced on the CCKW chassis including dump truck, water and fuel tanker and many others.
Early production of the "Jimmy" had a sheet metal steel cab or "hard top" with a steel bed. In mid-1942 wood beds were introduced, then replaced by a wood/steel composite bed in January 1944. After July 1943 the cab was "soft top", with canvas half-doors and roof. This reduced the steel content and made the CCKW more compact for shipping when the cab was folded down. Many other small changes were made during the long production run.

Comment by 'deadline' notes that this unstamped plate must be a reproduction since, a) in 1942 CCKWs were made by the Yellow Coach Manufacturing Co. (owned by GMC) while GMC did not appear as the sole manufacturer until 1944-45, and b) brass data plates were not used on production trucks, zinc data plates were.
