Okay, I understand now. You may try searching rod magazine web sites like
www.rodandcustommagazine.com I know as far as a primered look many use John Deere(the farm & lawn implement company)Black. It's flat finish, but holds up well.To give that well used look use a flatener to dull up the finish of the color you use. Check with a paint supplier in your area.The rest is up to you as far as "rust" or faded,scratched out paint look.
