This works great (recommended to rewire for safety). The switch at the bottom finial turns it off and on. To add light bulbs, you unscrew the bottom hook finial and turn switch.  This model was made before the pull-down fixtures. It uses a weight to adjust the height of the lamp instead of the retractable egg. If you want it lower, you raise the weight above the saucer. It's missing the back half of the bracket to attach to the wall. Saucer has some wear (pictured). It takes 2 light bulbs (not included). It's a prime example of the atomic space age.
