Vintage French opalescent glass wavy coolie ceiling light shade + fittings

An original vintage French wavy coolie shade made from a clear opalescent glass, which we have completed with an antiqued brass gallery and new brass bulbholder.   The glass is very beautiful, clear but with an iridescent hue when the light catches it.  The shape from above is very floral - it's a truly lovely piece.  It's hard to date these shades precisely, but we think this one is probably from the 1950s.

We search antiques fairs and shops in France to source these and similar shades.  We think they would look absolutely beautiful in just about any room, and also in a shop or café.  

In excellent condition, with no chips or cracks but please note that minor imperfections are inevitable with items of this age and which have been manufactured in small batches with a lot of hand finishing.  

Measures approx. 24cm diameter x 7cm max height.  Bulbholder is a B22 bayonet fitting.  Electric flex and bulb are not included - this listing is for the shade, the brass gallery and the bulbholder.
