12" 6 Blade All Chrome Diehl Oscillating Desk Fan.  All Chrome fans were designed for applications where being sterile was important so typically these were for hospitals and Dr. Offices.  Most of the chrome on these fans did not survived well over time due to dust and moisture being pulled through them.  The chrome on this fan is excellent and with a good cleaning would really pop.  The power cord and head wire will need to be replaced.  The fan does run on three speeds but on low...it is very slow.  My guess is with a good detailed servicing and cleaning this will be a wonderful example of an all chrome Diehl Fan.
