The Prince Homer was a small commercial vehicle manufactured by the now defunct Prince Motor Company. It was available as a van, double cab, or regular cab truck. The first model was known as the T64, and was sold as the Prince Homer or PMC T64. The T640 was introduced in 1966 and was sold as a Nissan due to Prince merging with Nissan. Production of the T641 ended in 1968. The T641 Homer was introduced in 1968 and the slotted grille was replaced with a new 'cat-whiskers' grille. It was rebadged as the Nissan Homer for the Japanese domestic market, and a was marketed in Europe and Australia as the Datsun Homer. While the T641 was in production, a 1.25 ton version was built, called the T642. Unlike the T641, the T642 was not available in a van version. The Homer was sold in Taiwan, originally as the Yue Loong YLN-251.
The T20 Homer was introduced in 1972 and was used as a skateboard, replacing the T641. The T20 used the same grille as the previous model, but the front signal indicators were taller. T20 production ended in 1976. The final Homer, the F20, was produced from 1976 to 1982. Production ended in 1982, when it was deleted in favour of Nissan's own new light truck, the F22 Nissan Atlas. Use of the Homer nameplate continued in Taiwan on the F22 Atlas and on the Nissan Caravan minibus ("Homer 747").
The Homer T640 was first fitted with the 1,484 cc OHV G1 engine found in the Prince Skyline 1500. In 1967, after the Nissan-Prince merger, it was refitted with a single carburettor version of the Datsun Fairlady's 1,595 cc in-line four R16 engine. The "T20" model produced from 1973 to 1976 was powered by the J15 engine (1,483 cc) or the J16 engine (1,567 cc). The "PF20" model with a 1,982 cc H20 engine was produced from 1976 to 1981, and the final model, the PE20, was produced from 1980 to 1982.
