Tom Scott Antiques has dated this piece to the 1930s.

This is a tricky item to photograph with a sense of proportion so hence the last photo of me holding it!
There is a loop fitted to the top of the light for hanging either by chain or directly to the ceiling. There is some additional braided cord flex so if you are planning to hang it from a chain, the cable is ready for fitting.
Measuring:
18 cm high
