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

They have a crackle glazed finish and you will see in one of the detailed photos showing a very small chip which is not a structural issue, but has just lost a little of the glaze. I will disguise this as best I can, but you can always turn the lamp so this is at the rear and hidden!

They have been re wired and are ready for use, the shades are just examples for scale.
Measuring:
23 1/2 inches or 60 cm to the top of example shades
14 inches or 36 cm to the bulb holder
5 1/2 inches of 14 cm diameter of the base
