antique holophane type prismatic clear glass shade for industrial lamp or pendant light

Holophane style early 1900s vintage glass shade with crimped edge, prismatic rib optic design. This is marked Wellington at the fitter edge as shown.

This would work well for a simple pendant light or industrial style work light fixture. It's 4 1/2" tall, 7 1/2" across the opening, 2 1/4" across the fitter.

There's a few tiny nicks and fleabites to the surface of the ribs, not visible at all. Overall this shade looks very good, nice and clear without discoloration.
