This model is the Wells-Brimtoy Box Truck in cream and red. This item is friction driven. The company also produced non-friction driven toys of the same size (approximately 3.75 inches or 82mm long).
The model has a diecast plastic chassis with pressed metal rear body. It has been shaped with rudimentary representations of the body lines. There is no glazing. At the front is a cast representation of the grille. The rear body is lithograph printed to represent the rear box and has signage that reads "Speedy, Transport Co." on both sides, and "Made in Gt. Britain" at the top of the rear cream "ramp" and a cream on red numberplate [AW 563]. The roof has lithographed roof vents.
The original black plastic wheels are still on the model, mounted on steel axles. The front and rear axles pass through the base, the rear axle also passing through the friction drive motor.
The base plate is a single piece, pressed tin unit. It has been press fitted to the body and the plastic body pins melted to hold it to the body. It appears to be plated. There are no manufacturer's marks but the country of origin details are on the rear top of this model.
I do not know exactly when this item was issued but believe it to be between the 1950s and 1960s.
