Here are the models for the rear of the Delorean from Eaglemoss 1:8 scale.
You have here 5 models in one, very good way to save money on the shipping!!
As you know, you will have to paint these models by yourself.
For the orange tube it is a bit more specific and I used this color to be accurate :

Otherwise, the other models will be in a metallic paint, red paint, grey and black paint.
