Swallow Sidecar Company

Swallow Sidecar Company, Swallow Sidecar and Coachbuilding Company, and Swallow Coachbuilding Company were trading names used by Walmsley & Lyons, partners and joint owners of a British manufacturer of motorcycle sidecars and automobile bodies in Blackpool, Lancashire (later Coventry, Warwickshire), before incorporating a company in 1930 to own their business, which they named Swallow Coachbuilding Company Limited.

Under co-founder William Lyons, its business continued to prosper as S.S. Cars Limited and grew into Jaguar Cars Limited. The sidecar manufacturing business, by then owned by a different company, Swallow Coachbuilding Company (1935) Limited, was sold by Jaguar in January 1946 to an aircraft maintenance firm, Helliwell Group.
