vintage industrial hanging pendant light shade, flat reflector white milk glass

Early electric vintage shade for an industrial style hanging light fixure... this is properly an antique, over 100 years old. It's hand blown milk glass, flattish in shape to reflect the light down to the work area below the fixture.

It's been used but is in very good condition without damage, a good piece of authentic architectural salvage. Measures 9 3/4" in diameter, 2 1/2" across the fitter.
