Here are a few photos of the mandibles, taken directly from the original prop in the Lucasfilm archive. If you are custom-painting your model, you can use them for your reference to how they look when attached to the framework and painted.
If you look closely at the first 2 images you will see the blue screen which means the images were taken at the time of filming TESB. You can also see the part from Tamiya’s 1/700 King George V over hanging the underside of the starboard mandible. This part and another from the KGV next to it are missing from the DeAgo kit.
