A HISTORIC vehicle buff is tracing the story of a rare 1930s sports car with a chequered past.
David Swann, who works in the transport design department at Huddersfield University, also wants to learn about Huddersfield's One Tree Motor Company.
Mr Swann, 37, hopes to find out what happened to the Singer type 9 - registration number KV5670.
It was among a trio of vehicles, painted red, white and blue, driven by a female team racing at the Brooklands circuit in Surrey in 1934.
The sports cars were part of a unique production run of specialist race cars - only five were ever produced.
Standard production models of the Singers now sell for about £15,000.
With 972cc engines they had a top speed of almost 70mph.
The red car was sold days after racing at Brooklands to the One Tree Motor Company along Northgate and Bradford Road in Huddersfield.
It surfaced in Leeds a year later to be bought by a Robert King-Clark who raced at Filey before trading it in at a garage in Bradford.
The car was owned by a Bradford motor engineer George Sherwen in 1946.
Another of the three cars, the blue one, surfaced in the 1970s.
The whereabouts of the remaining white vehicle are completely unknown.
Mr Swann, who owns a Singer with the registration plate KV5975, said: "I believe that I know somebody who thinks they have got the remains of the red car."
He hopes to write an article about the car's life and is trying to put in the missing parts of the history in terms of what happened to it in Huddersfield, how it got to Leeds and what has happened to it since.
He said: "There's been a lot of rumours and myths about the history of these cars and it's putting that record straight."
