context_page_description: Associated Equipment Company was a British vehicle manufacturer that built buses, motorcoaches and trucks from 1912 until 1979. The name Associated Equipment Company was hardly ever used; instead it traded under the AEC and ACLO brands.
context_section_description: Y Type
  AEC's first purpose-built commercial vehicle, the Y Type was introduced in 1915. The improved YA Type appeared in 1917. More than ten thousand of these vehicles were supplied to the War Department by 1919. Many of these were acquired by civilian operators following the war. YB and YC Types continued in production until 1921.

  The AEC Roadtrain was an experimental early 1930s road train.
  Majestic
  There 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 110 bhp (82 kW) 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 It remained in production until 1948 when it was superseded by the Mk III, which was mechanically similar, but had the Park Royal cab.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.
  Mammoth, model 667 (1930–34) - 4x2 cabover
  Mammoth Major 6 Mk.I/II, models 668 (1930–35), 366/O366 (1935–48) - 6x4 cabover (Mk.II from 1934)
  Mammoth Major 6 Mk.III, models 3671/3672/3673 (1948–60) - 6x4 cabover ('tin front' cab from 1955)
  Mammoth Major 6 Mk.V, models G6 (1959–66) - 6x4 cabover
  Mammoth Major 6, model TG6R (1965–78) - 6x4 cabover (Ergomatic tilting cab)
  Mammoth Major 8 Mk.II, models 680 (1934–35), 386/O386 (1935–48) - 8x4 cabover
  Mammoth Major 8 Mk.III, models 3871/3872/3873/3881/3882 (1948–61)- 8x4 cabover ('tin front' cab from 1955)
  Mammoth Major 8 Mk.V, model G8 (1959–66) - 8x4 cabover,
  Mammoth Major 8, model TG8R (1966–78) - 8x4 cabover (Ergomatic tilting cab)
  Mammoth Minor, model 366L (1936–41) - lightweight 6x2 cabover
  Mammoth Minor, model TG6RF (1965–67) - twin-steer ("Chinese six") 6x2 cabover (Ergomatic tilting cab)
  Normal control variants of the Mammoth family were also available, although much less common that the cabovers:
  Mammoth Major 6 Mk.I/II, model 266 (1930–36) and 366 (1936–48) - 6x2 normal control
  Mammoth Major 6 Mk.III, models 2671 (1948–60) and 2621/2631 (1956–62) - 6x4 normal control
  Mammoth Mk.III, model 2421/2431 (1956–62), 4x2 normal control
  Mandator
  The AEC Mandator name was originally used for medium-duty models in the 1930s, but in 1949 the Matador 4x2 was renamed Mandator. The name was used for the heavier AEC 4x2s until the end of production in the 1970s, and was especially popular as a tractor unit.
  Mandator, model 669 (1931–35) - medium-duty 4x2 cabover
  Mandator, model 672 (1931–32) - medium-duty 4x2 normal control
  Mandator Mk.III, models 3472/3474/3475 (1949–55) - 4x2 cabover. Successor to model 3471 Matador.
  Mandator Mk.III, model 2472 (1949–61) - 4x2 normal-control
  Mandator Mk.III, models 3481/3482/3483/3484 (1955–61) - 4x2 cabover ('tin front' cab)
  Mandator Mk.V, model G4 (1959–66) - 4x2 cabover
  Mandator, model TG4 (1965–78) - 4x2 cabover (Ergomatic tilting cab)
  Marathon
  The Leyland Marathon (1973–79) was a high powered 4x2 or 6x4 tractor unit with a modified Ergomatic cab, which was built at the AEC factory in Southall. A few were given AEC badges to satisfy individual customer preferences. The Marathon name had formerly been used on a Maudslay bus chassis.
