Mack NR

The Mack NR was a heavy 6x4 cargo truck of the 1940s, designed and produced by Mack Trucks and used mainly by the British Army to move cargo and materiel over long distances in the Second World War. The British Purchasing Commission ordered it in the United States, and because every order received its own number the type appears as NR-1 to NR-20. The early trucks had a closed metal cab and a six-cylinder Mack ED engine of 131 horsepower driving only the rear wheels through a five-speed gearbox, while from the NR-8 an open cab with a canvas roof replaced it. The NR-4 was a tank transporter. In total 16,548 were built, and many NR trucks carried war supplies through the Persian Corridor to the Soviet Union.
