well the company ceased trading in 1954 after ford took over briggs body builders who were the body suppliers for Jowett Cars Ltd. so in fact no part of jowett cars was around in 1998 ...
as quoted from british museum website
Founded in Bradford, Yorkshire by Benjamin and William Jowett the company was to last for over 50 years.
They built a prototype engine in their fathers Bradford business premises in 1898/99. It was fitted to a locally owned buckboard in 1901. Later in 1901 the brothers took on a partner Arthur V Lamb and started in the cycle business. They also produced a 6 hp water-cooled engine to be fitted as replacements for local vehicles and soon had a reputation for reliability.
In 1904 larger premises were acquired and the company became The Jowett Motor Manufacturing Company. In 1905 they designed and built their first complete car. Production of this tiller steered car did not start until 1910, and had a steering wheel fitted from 1913. The outbreak of war halted production in 1914 and the company turned to munitions. Wartime profits allowed a move to Springfield Works, Bradford Road, Idle, a small village outside Bradford and the name became Jowett Cars Ltd.
Car production started again in 1920 and Jowett became a public company in 1935.
Benjamin retired in 1936 and William severed connections with the company in 1940.
War caused an end of production in 1940 and they built machine tools and aircraft components for the duration. Plans were made in 1942 for an up-market saloon designed by Gerald Palmer, who had joined the company in 1942, and were to become the Javelin in 1946. This car was capable of 80 mph and over 30 mpg at a time when other manufacturers were still re-introducing pre-war models.
For the first thirty years all the cars had twin-cylinder engines and the basic design continued until 1954 in Bradford vans.
When Ford took over Jowett's body supplier Briggs, an attempt was made with plastic bodies but to no avail. The company ceased trading in 1954
