Brough

William Edward Brough began motor experiments at Basford, Nottingham, before the turn of the twentieth century. A small four-wheel car is recorded in 1898, followed by a motor tricycle using a 2½ hp De Dion-Bouton engine and belt drive to its rear axle. Corporate foundation dates vary between 1899 and the first motorcycle's documented completion in 1902; the catalog uses the first known vehicle year for marque history while retaining 1899 as the likely organized-business date in narrative. William's sons William junior and George later joined him. Brough became primarily a motorcycle manufacturer, unusual for developing many engines in-house. The first motorcycle carried a single-cylinder engine from its down tube. By 1908 the range included proprietary 2½ and 3½ hp singles and a 5 hp V-twin; a 6 hp V-twin followed by 1912. The same year Brough built an 8 hp V-twin for a light vehicle called the Monocar, the final named automobile program before car output ended by 1913. Surviving histories do not disclose whether that Monocar used three or four wheels, and no specifications are invented beyond its engine. William's motorcycle engineering then concentrated on a longitudinal overhead-valve flat twin announced in 1913. The 497 cc version placed its magneto above and two-speed gearbox below the crankcase, with chain primary and adjustable-pulley belt final drive. It displaced other engines by the end of 1914 and evolved into larger 810 and 947 cc forms after the First World War. George Brough, already a racer and development driver in the family firm, disagreed with his father over the expense of a new high-performance 500 cc flat twin and left in 1919. He established the separate Brough Superior company at Haydn Road, adding 'Superior' to signal his quality ambitions. Brough Superior motorcycles and its later 1930s cars are not models of the original Brough marque. William's firm continued flat-twin motorcycles through the mid-1920s. Sources variously put final manufacture in 1925 or 1926; Brough Superior acquired or absorbed the original operation around 1925. Three automobile families are retained: the one-off 1898 Small Car, the De Dion-powered 2½ HP Motor Tricycle, and the 8 HP Monocar. Sparse evidence of unspecified additional four-wheel vehicles is acknowledged but cannot support fabricated names or duplicate rows. The history distinguishes the family relationship, company succession and badges while leaving the extensive motorcycle model range outside this automobile catalog.
