This model is the Imperial 06 Fuel Tanker in Yellow.
This is a one piece casting and with no opening parts and all features cast into the body. The front is marked with the Imperial Crown logo, "Imperial", "© 1975" and the rear is marked with "Hong Kong". There is no glazing as the windows are also filled in with the body material (vinyl).
There is no base plate as such — the body casting is open to the under side and strengthening bars are in place to hold the soft body's shape. It is not marked with manufacturer or country of origin details.
All wheels are one piece, soft vinyl in black, attached to a rounded axle that passes through struts molded on the underside of the body and the wheels.
This model is thought to have been issued circa 1976.
