Here it is the right shoulderpad of the juggernaut.
I´ve painted it as the rest of the juggernaut but i´ve added some khadorian inscriptions in the right shoulder, just to add a bit of colour in the overall model.
As you can see the inscription has the same style as the "magic" in the pictures in the book, as you can see in this image.
Here is another shot which show better the inscriptions.
