I have the original radiator cap designed by Arthur Kopperud. It states on it that a patent is applied for A. Kopperud 1922. The front says "Safety Goddess". I believe it is the likenes of my great aunt Norma Kroes whom he married about 1927. He died about a year later. Would like to get a copy of the patent and know if it was ever used on a car? Any ideas?
