In 1924, Tokyo Ishikawajima Shipbuilding and Engineering, a forerunner of Isuzu Motors, produced the 1.5-ton CP truck in Japan through a tie-up with Britain's Wolseley Motors. The vehicle played a pioneering role in the establishment of a domestic automobile industry in Japan in the mid-1920s.
The preserved vehicle was returned to Isuzu from the National Science Museum in 1991 and was completely restored. It is now maintained in full operating order and is on display in the entrance hall of the Isuzu headquarters. |
