This is a awesome 1950s Mid Century Modern Vornado window fan. It can be converted to a twin compatible window fan. Fan is solid metal and has been tested and works great. It has a metal stand that can allows it to be placed on a desk or table or mounted in the window. Paint looks good, has some scuffs and wear with age, all exterior parts have been cleaned including fan blades. Really solid and runs great! See pictures for details on flaws, awesome industrial fan for display or use. Not sure of exact age but please don’t hesitate to message with any questions.
