1914 - 1923
The Mercury was a good example of the 'large car in miniature' theme exemplified by better-known makes such as Calcott and Singer. It was powered by a 1298cc 4-cylinder engine said to be of Medina-Hastings manufacture, i.e. in their own works. A new company was formed after the war, operating from a different address but still in Twickenham. A 2-seater with the same engine was shown at Olympia in 1919, and another Mercury appeared on the stand of coachbuilders W.H. Arnold with 2-door all-weather saloon body. Apart from this, most coachwork on Mercury chassis was made by Mercury themselves.
Like many others, the company was a victim of competition from mass-production cars like Morris.
