9" R&M Model 7300 Wall Mount Phone Booth Fan.  Really neat little fan, these were mounted on springs to avoid vibration noise from the fan while mounted to the phone booth.  This example has been professionally serviced by Time Past Fans (Paul Graves).  The finish appears to be an over spray on top of the original.  It displays well as is or could be professionally restored.  The brass has been painted at some point and has started to patina.
