The MG F-type Magna is a six-cylinder-engined car that was produced by MG from October 1931 to 1932. It was also known as the 12/70. Looking for a car to fill the gap between the M-Type Midget and the 18/80, MG turned to another of the engines that had become available from William Morris's acquisition of Wolseley. This was the 1271 cc 6-cylinder version of the overhead camshaft engine used in the 1929 MG M type Midget and previously seen in the 1930 Wolseley Hornet and had dummy side covers to disguise its origins. Fitted with 1 in twin SU carburettors it produced 37.2 bhp at 4100 rpm at first, later increased to 47 bhp by revising the valve timing. Drive was to the rear wheels through a four-speed non-synchromesh gearbox of ENV manufacture. The chassis was a 10 in longer version of the one from the MG D-type with suspension by half-elliptic springs and Hartford friction shock absorbers all round with rigid front and rear axles. Wire wheels with 4.00 x 19 tyres and centre lock fixing were used. The car had a wheelbase of 94 in and a track of 42 in. With its sloping radiator and long bonnet the F-Type is an attractive car capable of reaching 70 mi/h. 188 of the cars were supplied in chassis form to outside coachbuilders such as Abbey, Jarvis, Stiles and Windover.

F

The original F was restricted by only having 8-inch (200 mm) brake drums, which, with its 4-seat bodies, was not really adequate. Many F1 cars have subsequently been fitted with the larger F2 brakes. The four-seat tourer cost £250 and the Foursome coupé cost £289.

F2

Introduced in late 1932 the F2 was the open 2-seater car in the range. It also got much needed enhanced braking by fitting larger 12-inch (300 mm) drums all round. The body with straight-topped doors came from the J-Type Midget.

F3

The F3, also introduced in 1932, used the same brakes as the F2 but had the 4-seater tourer and Foursome Coupé bodies fitted. The engine cooling was improved by changing the cooling water flow.
