Dennis Flather was a wealthy Sheffield steel merchant who first competed in a Marwyn fitted with a Scott engine and other modifications which he called "Marott" (MARwyn scOTT) in 1948. Given that the Marwyn chassis was somewhat lacking and the Scott engine was rather less powerful than a JAP, the combination was less than successful. Replacing the Scott with a Vincent Grey Flash engine for 1950 and renaming the car the Blue Flash failed to substantially improve things.
For 1951, he built his own car along the lines of a Cooper Mk V but with fairings over the front suspension and rather more ground clearance. Initially, it ran with an HRD engine but this did not produce the required power and a JAP was substituted. Dennis' business was steel and the car was formally called the Flather Steel Special, something that was not officially permitted at that time.
Spike Rhiando was the primary driver, having abandoned his Trimax, known results being:
Dennis had a range of automotive interests, including being a founder member of BRM, and in 1954 he hired former speedway rider, Australian, Bill Harris to maintain his cars and compete in the 500. The second Flather Special was built and driven by Bill in 1954, a brave decision given the Cooper domination by this time. Much lower and clearly Cooper influenced, it used a long stroke Manx engine with wishbone and coil front suspension at the front and a de Dion at the rear located by twin trailing arms. Bill had rather more success with this car and continued to compete through to 1959. It went to the US after this and appears in the hands of Jim Haynes through 1960.
