Alldays & Onions was an English engineering business and an early automobile manufacturer based at Great Western Works and Matchless Works, Small Heath, Birmingham. It manufactured cars from 1898 to 1918. The cars were sold under the Alldays & Onions name. Alldays also built an early British built tractor, the Alldays General Purpose Tractor. After the First World War the cars were sold under the name Enfield Alldays. Car production seems to have ceased in the 1920s but the manufacture of many other items continued. The company became part of the Mitchell Cotts Group. History Engineering businesses: Onions (formed by John Onions in 1650) and William Allday & Co. (formed by William Allday in 1720) joined in 1889 under the ownership of Alldays & Onions Pneumatic Engineering Company Limited. They made engineering and blacksmithing equipment. Like many such companies at the time they turned to bicycle manufacture and sold a range under the Alldays name. They also started making motorcycles in 1903 under the Alldays-Matchless name; these had no connection with the London-based Matchless company, and in 1915 presumably following representations from them, the name was changed to Allon. Manufacture of these continued until 1927. Alldays and Onions produced its first car in 1898. The Traveller, a quadricycle made in private and commercial forms, was steered by a wheel. It had an unsprung rear end, power generated by a 4 hp De Dion single-cylinder motor. However, series production did not start until 1903/4 with the 7 hp model. Larger commercial vehicles of up to 5 tons were also made in the years preceding the first World War and saw service during the conflict. Alldays hit commercial success with the 1.6-litre, vertical-twin side-valve 10/12, which was made from 1905 to 1913. It was popular with commercial drivers and did well in period formula events and hill-climbs. A 16 hp 4-cylinder joined the lineup in 1906, and in 1908, the Enfield Autocar Co. was acquired. Shortly afterward, the range was rationalized, with most models being sold under both brand-names. The Alldays contribution to the equation was the well-established twin- and four-cylinders that put out 14 and 20 hp, always shaft-driven. A 30/35 hp six-cylinder was listed from 1911 to 1914, compressed-air starters being optional in 1911. In 1913, the 990 cc V-twin Midget cyclecar was introduced, featuring air cooling and shaft drive, selling at £138.10s. (About £ today). An 1100 cc 4-cylinder
