Justin, that's an interesting bulb. At the end of the 50's when knotty pine paneling and early American furnishings were really beginning to take hold, various manufacturers introduced complementary styled bulbs to create the kerosene lamp chimney look without the need to upgrade an existing fixture. The Westinghouse Spun Glow comes to mind. Typically the glass was tinted light yellow and ribbed, but this one is unique because of it's smooth, white appearance, and the fact it uses an oversized bulb support around the base. Are there any markings stamped into the metal? This was also about the time the Japanese were trying to understand the latest American trends and were introducing competing, albeit cheaper looking, and poorer quality, alternatives. Abco comes to mind.
