What Paint?

yes if the horn pad is kind of a satin black the wheel should be the same right?
I would say so. I think the wheels are cast in color when made and not painted. They were a medium gloss and not base/clear like my restored one is. Kind of hard to duplicate but the restorers do. You might want to poke around on the internet for restoration shops. Their photos and captions might give some information what they use.
