I sold the two I purchased last week on e-bay.
One was a G.E. very similar looking to your Emerson. No cord and
not working, a little less rust. $56.00 plus the shipping.
The other was a Century, older with brass blades and not working, no cord
and that one only went for $41.00 plus the shipping. Brass blades are
usually more desirable. Both had 16 inch diameter blades.
If yours is in working condition, I think it would be fun and worth it to
paint it all pretty again. Restored fans like these can fetch up to $250.00
and sometimes more, sometimes less.
