On the Wheels, you mentioned Bullets and I'm not sure if that is a single big bullet. A style years ago was called a "Spider" that had a chrome cover over the Lug Nuts and the center had a small bullet. To give you an idea of what I'm thinking, the mounting was held in place by the Lug Nuts. The chrome cover had small almost unseen screws that attached the chrome cover to the mounting bracket. These first started appearing in the '50's about the time that Chrome Wheels were becoming common. These would hide the Lug Nuts that usually weren't so pretty.
