Retired vehicles.
Following the Second World War, Hong Kong Police vehicles, with exception of motorcycles were generally painted in "battleship" grey. The livery changed to dark 'navy' blue following the Queen's bestowment of the "Royal"title to the force in recognition of their services during the 1967 Communist disturbances.
