Hi again.

I was wondering if anyone knew the best process to restore the dark patina on the metal bezels in an Astor 1948 console radiogram. The unit has two such bezels used (voice/widerange/bass and radio/gramo), but are scratched and badly worn, so some of the underlying metal (copper?) is showing through. The underside of the bezels are a matte black, whereas the face appear to be a polished dark brown/near-black colour. - The screws are also coloured to match the bezel.

I'm going to assume the bezel would originally have appeared dark brown, as the dials themselves are a chocolate brown colour - but that may be an incorrect assumption.

I've seen products online like "Birchwood Casey Brass Black Metal" which look like they could do the job, but was hoping I could get some advice from the experts here.

Additionally, what colour would the stamped (recessed) text be originally. I can't tell if it was white or some gold colour.

Happy to provide photos if required.

At this stage of the game, I'd kill for a colour reference photo.

Thanks again.
