Addison Motor Company

The Addison Motor Company was an English automobile company based in Liverpool. James Harold Atherton was the sole proprietor and works manager from 1903 until 1918.^[1]

The 6+1⁄2 hp (4.8 kW) two-cylinder engine was controlled by variable-lift inlet valves. It was promoted as "the Mercedes of the tri-car world".^[2][3]

The company also produced motorcycles in 1904–1905.^[2]

The Addison touring car and tri-car were shown and well received by The Motor at the ninth Liverpool Motor Show.^[4]

The Addison tri-car won a silver medal at a hill-climbing contest held by the University of Liverpool Motor Club on 13 July 1905.^[5]

In January 1912, it was reported that the company was so successful that they had to open a separate showroom at 7 Berry Street in Liverpool for their Alldays and Phoenix cars.^[6]

Another car the company sold was the Speedwell.^[7]

Around 1922, the company expanded to a larger garage.^[8]
