This piece is a small scale HO Scale or 1/87 Scale model. It measures 4 inches long from the back of the vehicle to the front of the scoop.  From wheel to wheel it measures about 1.25 inches wide; so this is a very small model that fits on the palm of your hand.

 

The wheels and can roll freely and smoothly. The vehicle has articulation on its center and can pivot. The articulations in the arm can move. The scoop also has movement. As you move each articulation the pins (pistons/cylinders) also move accordingly just like on the real thing.

Two extra optional attachments are included for the arm.

THIS IS NOT A TOY. It is very small and fragile. It is made mainly for display purposes.

The model comes in a beautiful multicolored metal can. The can is a much collectors' item as the model itself. 

The can measures 6.25 inches long, 2.75 inches wide and 3.75 inches high.
