The box shown here is for the Dinky Toys #439 Ford D.800 Snow Plough & Tipper Truck model.
It is an 'end-flap' type box utilising a thicker grade of board than was used on the car model boxes at that time.
Also included with this box is the insert / packing piece as supplied with the original boxed models.
All colour variations of this model were originally supplied in the same box.
