The Virden Company produced a huge number of lighting fixtures during the 1930s and beyond.
One of their most popular lines was their Winthrop Series, introduced about 1930. As a result, I am always coming across Winthrop fixtures, including the one shown here, as well as chandelier versions, 3-bulbs, 2-bulbs, and sconces.
For me, the fixtures are a joy because they normally retain their original rich polychrome finish, and (I love this!) they are easy to rewire! There are fixture I avoid because long experience has taught me that they are a nightmare to rewire!
