In 2001, along with the engine, several wrought iron structural members associated with it were also recovered. In the image below on the left, is a recent x-ray of a fragment of engine bed plate, which revealed a series of relatively intact rivets.

If you look closely at the x-ray, you can see the outlines of the rivet heads, which are hidden below concretion seen in the photograph of the artifact on the right!
