Decorative 20th Century Lamp With Shade

Decorative 20th Century Lamp With Shade. 
Missing The Circle For the Lampshade Holder. 
The lampshade is a little odd, but I bought it with it so thought it would be good to sell together. 
It is working order but hasn't been PAT tested. 
With the shade it measures 57 cm and without 37 cm.
