The Triple M series of MG’s all belong to a family of models that commenced with the 1929 MG Midget and continued through to the mid-thirties via a long string of four and six cylinder OHC engined cars that forged the marques identity.
Following on from the MG PA depicted in Triple M corner no.124 is this MG J3 Midget (JB 1047) which was featured in a road test article in the May 1933 edition of Motor Sport magazine. (pages 325/326) The 750 cc J3 reputedly had a top speed of 93 mph and was supercharged via a Powerplus 6A unit. A heavier duty crankshaft to that fitted to the J2 was required in order to cope with the forces associated with a power unit that could spin to 5500 rpm. The test was carried out at Brooklands in the early spring of that year in weather conditions that could not be described as ideal, neverless the reporter was fulsome in his praise of the car’s performance.
