antique 1910 vintage ceiling fixture pendant light, white glass shade

Vintage 1910 pendant light fixture with period white glass shade about 8 1/2" in diameter, It's about 25" long end to end.

The old brass socket looks good, and the turnkey switch works fine. The cord and old porcelain fixture show wear and a lot of soil from years in a factory work shop setting, and there's some chips and roughness to the fitter edge on the shade (not visible unless it's removed from the fixture).
