Zenith Metal Bezel paint/tinting/toner?

[hfrazier]

Hi Everyone,
I was wondering what kind of paint(?) was used to give the metal covers and bezels their gold/brass tint. Does anyone have an idea as to what I should use, or even what it's called? I'd like to sand, polish and re-paint it if possible..

I have attached a picture to help match the color. I suppose it used to look as good as the inner side of the hinge at the bottom of the pic.

Thanks in advance!
