All British (United Kingdom) - AllCarIndex

The All-British Car Company was established between 1906 and 1908 in Bridgeton, Glasgow, by George Johnston, who had previously been a partner at Arrol-Johnston. The company aimed to produce automobiles featuring a complex 8-cylinder engine, which was designed on the same opposed-piston principles as the early engines developed by Arrol-Johnston.

In 1907, the All-British Car Company showcased a vehicle at the Agricultural Hall Show, which marked a significant moment in its brief history. Johnston had ambitious plans to manufacture 75 cars annually; however, it appears that the show car may have been the only model produced by the company. In addition to automobiles, Johnston also constructed a bus equipped with a 4-cylinder engine that operated in London for a limited period.

Despite its short-lived existence, the All-British Car Company represents an early attempt at automotive manufacturing in the United Kingdom during the early 20th century.
