12" Green Verity Orbital Double Lever Oscillator.  These are just the greatest design in oscillators and this is the most desirable of the orbitals.  This fan has an older restoration and unsure if this was the original color.  The Blade, Cage and Accessories are all brass plated.  The plating has wear on it and may have been original to the fan.  The guard has several old repairs on it and could stand use some touching up.  The fan could also use a good "going through" as it is hard to start and runs slower then it should.  I would think a good disassembly and cleaning would get this back into correct operation.  If you have wanted an Orbital Oscillator, this is the version to have.
