Westclox Baby Ben Style 4 Base Bottom Color Variations

Most Style 4 Baby Ben bases are painted gold on the bottom. Starting in 1937, some are painted the same as the case. Gold bottom bases have a brass nut in the center. Ivory and Gun Metal bottom bases have a nickel nut in the center. Some of the Ivory and Gunmetal bottom bases have a plated outside edge (like the gold bottom bases), others are un-plated.
