The formation into groups during the late 1950's covering many of the British marques meant they had duplication across their product range which led to inefficiencies. This was in contrast to the US owned brands with production units in the UK like Ford and Vauxhall. More rationalisation came when Standard-Triumph' was taken over by Leyland Motors when they had financial difficulties. BMH was then formed bringing together BMC - Austin, Morris, MG, Riley and Wolseley - and Jaguar. Not long after Rover was swallowed up with Leyland Motors. Chrysler of the US had no footprint in the UK and it took over the Rootes group which included Hillman, Humber, Sunbeam, Singer, Talbot, Commer and Karrier.
Towards the end of the 1960's British Leyland Motor Corporation (BLMC) was formed bringing together BMH and Leyland. During this time we had seen some iconic cars introduced to the market such as the Mini, Anglia, Morris Minor and the Cortina.
By the end of the decade Britain had slipped further back to fourth in the worlds manufacturing league.
Popular cars included th Jaguar MKII, MGB GT, Mini, Cortina, Austin/Morris 1100, Morris Oxford/Austin Cambridge, MG Magnette, Vauhall Victor, Humber Sceptre, Singer Vogue, Ford Zephyr, Triumph Spitfire, Triumph TR4.
Oxford Diecast has examples of some of these marques in its model car range, some being represented across different scales.
