JC

This British marque encompassed a succession of small manufacturers based in Yorkshire and later Kent, including J.C. Autopatterns, J.C. Sportscars, T&J Sportscars, R.L.T. Developments, and eventually White Rose Vehicles.

The origins of the marque lay with John Cowperthwaite, who, after producing his Moss range of cars, turned his attention to plans-built vehicles that customers could construct themselves. His first design was the Midge, a compact, traditionally styled roadster of simple construction, featuring an all-wooden body with aluminium engine side panels, a cast grille shell, and a fibreglass double scuttle. It was designed to fit a Triumph Herald or Vitesse chassis, though a separate chassis for Ford Escort components was also offered. Production of the Midge passed to T&J in 1989, returned to R.L.T. by 1993, and later moved to White Rose Vehicles.

The next plans-built model was the Locust, introduced in 1986, whose styling recalled the Lotus Seven. Its plywood bodywork was skinned in aluminium or Medite board, though an all-fibreglass version was shown in 1993. The car was typically built on a Ford base, though a Triumph Herald, Vitesse, or Viva chassis could be specially ordered.

In 1991, the range expanded with the Husky, a Ford Escort-based, jeep-style vehicle constructed from medium-density fibreboard. Production of the Husky was later continued by White Rose Vehicles.
