Leylands were purchased from the mid-1930s and made up a large part of the fleet by the beginning of the Second World War.
From the 1930s to the 1990s, the majority of vehicles in the Delaine fleet were of Bedford or Leyland manufacture.
Until the late 1980s, Punchbowl Bus Company were a loyal Leyland buyer.
Leyland manufactured many buses with semi-automatic transmissions, including its Leopard and Tiger coaches.
