Since we have not been told what it's based on I had a Google and found a site which included the following:
TK-102 (Mistral Sports Car Body): This is an exact copy of the Mistral sports car body that was introduced by Bud Goodwin to America in 1956. Bud later went on to create a company called “Sports Car Engineering” which sold the Mistral body under the “Spyder” name. Bud then went on to create his most famous company – Fiberfab – which continues to operate on the West Coast as of today.
Good friend Erich Schultz from Altadena, California studied the TK-102 in the picture and commented the following: “Geoff…it appears to have been a Jowett Jupiter Special. The pattern of holes on the wheels match the Jowett perfectly in configuration and number, and the extremely short hood with tall hoodscoop (which is entirely forward of the front wheels) matches the design of the horizonally opposed 4 cylinder engine of the Jowett. This may help in identifying who built this car and perhaps the driver who is pictured too. I also believe that the picture is from a car raced a few years earlier than 1960 – perhaps 1956 or 1957.” Thanks Erich!
Like all internet sources, it is not evidence, but whoever Schultz is/was he and I agree on the wheels and his further analysis looks sound.
