What type of Plating finish should there be on (1)--The Strap that holds the magneto in position, (2)--- The small diameter oil feed pipes from the crank case to the rocker box and (3)---The rocker box lid special nuts---they all dirty and old look and like unpolished chrome but are they supposed to be dull chrome or polished chrome or are supposed to be zinc plated ?.
