Here is a website that has info and some pics on the Die Cast metal model of the Cube.
You will need to scroll down a little way to find the pics on the models.
It seems that there are other colors of the Cube.
I need to check and see if there is another source to find the Cube die cast metal model in different colors.
here is the website address:

Check out the website and see if you like the site.
You can register on this website for free. When you first get to the website, you initially are a guest. It is a website for die cast metal model collectors.
Hope this helps.
