here's an animation of a light moving around the texture.
(Right-Click, Save Target As...)
here's a screenshot of it in real-time within 3ds max
To do this I used a combination of photoshop and modelling in 3d. For some details like the groove near the bottom, I modelled that in 3d. For the scratches and more subtle stuff, I used a photoshop manipultion of the original texture as a bump map in 3ds then used that with the modelled geometry to generate the normal map.
