Singer 9HP Roadster. Snger Motors, who can be regarded as pioneers of the British light car and have an unbroken record from 1911 in the production of light cars, have evolved what is perhaps the most important light car of today in their "Nine" Roadster model. Its powerful overhead camshaft engine fitted with a four speed gear box sets a new standard for light car performance. It is a car which is regarded as an outstanding example of the skill of the British automobile engineer.
