Tom Scott Antiques has dated this piece to the 1930s.
I have not over cleaned them, so they retain their aged look, but lightly cleaned and waxed which gives them a lovely smooth finish.

I have shown them with a pair of French drum style shades as examples to give a sense of proportion, but please note they are not included…but the price does include delivery within mainland UK.
Measuring:
32 1/2 inches or 82.5 cm to the top of the example 40cm diameter shades
22 inches or 56 cm to the bulb holder
5 1/2 inches or 14 cm square bases
