that looks like it might be an outline of a letter done with a chrome bevel. There are lots of tutorials on creating that type of chrome look.
In the inside of the letter are the wire textures, that could be 2 different layers behind the chrome letters. The diagonal lines look just like Aurora's "diamond wire" on their "engine turn CD" ..but the horizontal lines are not part of that so they could be easily added on a seperate layer, with a bevel effect.
The top layer (chrome lettering) has a shadow only on the inside. I'd do a layer style with a shadow that would fall to the outside also, but I'd save a selecting of the outside background around the lettering, then flatten a copy of the file when everything else is done, then use that selection I saved to delete the shadow on the outside of the lettering.
I think that look is really nice by the way & it inspires me to try something similar. Can you show us a pic with more of the original design?
Good luck & show us what you end up with.
