Background
Like the majority of Britain's motor manufacturers, Jaguar Cars, as William Lyons' SS concern had been renamed in 1945, commenced post-war production with a range of pre-war designs.
Essentially stop-gap models pending the arrival of an entirely new generation of Jaguars, these comprised the compact 1½-litre and the 2½/3½-litre models, retrospectively known as the Mark IV.
Built on a generous 120" (3,048mm) wheelbase, the Mark IV retained a separate chassis featuring beam front and live rear axle suspension on semi-elliptic springs, and Girling mechanical brakes.
The stylish all-steel coachwork was available in saloon or drophead coupé forms and featured the kind of luxurious and well-appointed interior that would become a Jaguar hallmark.
Used by SS Cars since 1934, the engine was Standard's rugged seven-bearing six which, in Jaguar specification, was fitted with a Weslake overhead-valve cylinder head and coupled to a four-speed manual gearbox. In 3½-litre form, it was a combination capable of propelling the sturdy Mark IV to over 90mph.
In the immediate post-war period, Government Minister Sir Stafford Cripps told British car manufacturers that unless they could guarantee to export 30% (soon rising to 50%) of their products, the government would refuse to supply them with steel.
This draconian directive had three principal effects: lots of UK car manufacturers withered and died; others turned to aluminium as the medium of choice for crafting their vehicles; and a few, like Jaguar, pursued overseas markets like their lives depended on it – which they did.
Which makes this RHD UK-market model a fairly rare car.
