What was the car company Jaguar known as before the end of WWII?

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 to own their business which they named Swallow Coachbuilding Company Limited.

Under co-founder William Lyons its business continued to prosper as SS 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 to an aircraft maintenance firm, Helliwell Group, in January 1946.

The continued success and expansion of their SS Jaguar range, in particular the sports and saloon cars announced in late 1935 would lead to its new name. Towards the end of the war on 23 March 1945 the SS Cars Limited shareholders in general meeting agreed to change the company's name to Jaguar Cars Limited. Said Chairman William Lyons "Unlike S.S. the name Jaguar is distinctive and cannot be connected or confused with any similar foreign name."
