LEYLAND OLYMPIAN 11M (non-A/C) ( KMB S3BL FW1440 )

[@chrischoy9]

sounds more like a Gardner engine. Bare in mind that KMBs leyland olympian exits in having Leyland/Gardner/Cummins engines. On the wheel, if you see a word under blue "Leyland" than it has a leyland engine. If the body of the bus says "Leyland" and the wheel has nothing meaning it silver that it will be a bus with Gardner or Cummins engine.
