ceiling fan (Spring Hill, Somerville)

Hunter ceiling fan with light
(sorry I didn't get a picture of the assembled fan)
five blades, 20" long, reversible -- white or light wood
light takes single bulb, cover 8.5" diameter
one chain for light, another chain for three fan speeds
This fan works but has seemed to be off balance, therefore too noisy to use in a bedroom except on low speed. In fact, this may be more than a balance problem. The fan was quiet for several years. Perhaps something internal needs to be repaired.
