were three distinct incarnations of the AEC Majestic: Majestic, model 666 (built 1930–36) - 6 ton normal-control lorry. Majestic, models 3521/3531 (1950–57) - 10-ton twin-steer ("Chinese six") 6x2 cabover. Majestic, model GB6 (1959–68), - 6x4 variant of heavy normal-control Mogul, built primarily for export and specialist uses. Mammoth The AEC Mammoth was introduced in 1930, being largest truck in the AEC range and the first to be available as a cabover. It was originally a 7/8 ton 4x2 lorry with a six-cylinder overhead valve engine developing on a wheelbase of 16 ft 7 in. A 6x4 variant was the "Mammoth Major". From 1934 a distinction was made between the lighter Mammoth Minor, and the heavier Mammoth Major 6 (6x4) and Mammoth Major 8 (8x2 or 8x4), which appeared in 1934. The Mammoth Major Mk II was introduced in 1935; the eight-wheeler could carry 15-ton loads. It remained in production until 1948 when it was superseded by the Mk III, which was mechanically similar, but had the Park Royal cab. Subsequent Mammoth Majors featured the Mk V cab, and finally the tilting Ergomatic cab. The original 4x2 Mammoth and lightweight Mammoth Minor were relatively short-lived models, but both names were later re-used.
