Hey Steve, it looks pretty good!

I see a few signs indicating it wasn't built with CSG. Might want to 
make those hex nuts a little less 'telling' by removing the smoothing. 
It's a matter of taste, though.

My first thought is to use some sort of proximity pattern to distribute 
the metal's reflection unevenly. All proximity patterns are costly in 
terms of time needed to render them though.

Next idea would be to use a turbulent bumps pattern to make some parts 
less reflective. Combine that with a slope pattern to add a little dust. 
Together, they should make that metal look quite old, possible a little 
abused.

TIA? Thanks in advance?
