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.
The 1935 MG PB has an engine that represents the zenith of pre-war development of the original 1928, wolseley designed and built 19 bhp Minor unit. While the MG PA engine retained it’s 847 cc, it did gain a three bearing crankshaft. This carried over to the PB model which now had an increased capacity, gained by enlarging the bore from the original 57mm to 60mm. This then enabled the twin SU unit to produce 43 bhp. Just 526 MG PBs were built. (LAT collection Autocar photoscan – Courtesy of Motorsport Images)
