Luke,
That is a great pic of the original paint on the horn button and what I assume is original paint on the steering wheel.
They look like a match.
As I have mentioned earlier, Rustoleum 7754 Anodized Bronze is as spot on of a match for the steering wheel, steering mast and apparently to my eyes, the horn button.
