My father had my steering refurbished for a Christmas present as it is nearly impossible to find a N30 in good condition. My question is whether the center piece should be semi or hi gloss. I think it's called the horn shroud. Same with the two buttons.

Photos of the original wheel off the green 68 L78 car. Surprisingly I have not cleaned it yet so its a little dirty but should answer your question.
