Holophane Glass Diffuser Hurricane Light Cover best Shade

This listing is for a Holophane Glass Diffuser Hurricane Light Cover Shade. Each Holophane glass cup cover measures 4 1/4 inches tall and is 6 inches across the top open rim, just under 2 1/4 inches best across the rim that sits in the fixture of your choice. Each is in good shape with no chips, cracks or other issues to the glass. No markings that I can find. See pics.

I have 3 of these each available separately here.
