Yeah, Immediately after I posted that, I realised that the default 
textures probably had an ambient set .. I was right :) .. I had a 
default finish ambient 0, but the default textures seem to explicitly 
have an ambient set.

Here's the new one, it's now just a little on the dark side, but at 
least it's looking metallic!

Cheers!

Much better.  A couple notes though
1) the rusted part seems to be reflecting too much for its level of 
corrosion
2) not sure what you're using for highlighting, but it's too diffuse to make 
a convincing polished chrome and brass, again here I prefer pureland style 
and not use the internal specular highlighting options but use visible light 
sorces instead and rely on reflection of the environment.  The 'true' feel 
of chrome is how it reflects it's environment.  However this may not give 
you the results you are looking for without background objects or scenery to 
reflect.  If you don't want to go through the trouble of building the 
environment, then adjust the specular highlighting to be much more sharp.
