Lancaster Antiques has dated this piece to the 1920s.

Lovely craftsmanship, and an excellent quality item.
THE SHADES ARE ALL ORIGINAL- there are three deep pink/dark orange flower/petal shades and a clear glass etched shade in the middle.
It is possible to use modern copies of the flower shades in opaque glass if the buyer doesn't like the original coloured ones.
It measures approximately 31" (79cm) in length and 21" (53cm) at the widest point across the shades and has been rewired to UK specifications.
