Would anyone be able to give some general guidelines in figuring the
value of a very old mechanical whistling bird in a cage?  It is a gold
colored cage, about 8 inches high.  A single black bird sits on a perch
inside.  When you wind up the mechanism and turn it on, the bird whistles
and the head moves back and forth.

I can find no name on the outside of the cage.  The bird has never been
restored, but still works fine.  I would guess it has been in the family
for 50+ years.  Thanks for any advice anyone might have.
