This model is the Tudor Rose No. 6355 Euclid Dump Truck in yellow and black with clockwork motor. At 185mm long it scales out to 1:38 scale approximately when compared to the real vehicle's specifications (total length 22 feet 10 inches [6959.6mm]).
The body is a greenish-yellow plastic and has a fixed bonnet and doors but tipping rear body. Black plastic radiator grille and lights are attached to the body work, as is the black plastic exhaust stack. The body is cast with detail such as a louvre vent on the bonnet, doors, door handles and hinges, and radiator cap.
There is no interior or glazing.
All wheels are of a one piece, black plastic, heavy duty tyre molding with a greenish-yellow plastic insert to represent the front and rear hubs.
The base plate and chassis of the model are a single, black plastic unit, shaped to represent additional features such as the fuel tank, gearbox, driveshaft and rear differential. It is marked with three circular marks on the under side. The first reads "Made in England", the second reads "This Items is a Tudor Rose Design" and the third reads "Tudor Rose Plastic Products". A separate black plastic lever has been attached to the base to facilitate the tipping action and is pressure fitted to the chassis. This lever is connected via a 45mm metal rod to the rear body. The base is held in place with two melted plastic rivets in the centre of the model and body locating lugs at the front. Folded tin tabs hold the clockwork motor in place at the front of the vehicle. The motor drives the front wheels of the model although the real vehicle was rear wheel drive as represented by the drive shaft and differential impression on the base. The motor is wound via a permanent key.
The model comes in its original multi-coloured cardboard box with three different images of the Euclid. Both end flaps and all four faces of the box are marked for the "15 Ton Rear Dump Truck", 2 faces carry "Made in England" and "Item No. 6355", and all faces and end flaps carry "Tudor rose Working Scale Model" but no mention is actually made of a scale for the model in question.
This model was probably issued in the 1960s and, as described above, is approximately 1:38 Scale.
