Measures about: 9" tall x 9" wide, clamping surface/opening is only 3/4" wide

Vintage used condition. Light was tested and is working at time of test with its original bulb. The bulb is original and I do question if it will make it with the post office throwing the packing around may mess up the element. But it will still be packed with lots of care. It is also missing one rubber stop and does have the usual wear for its age.
