Sorry, but I have no details on the designer and there are no markings to help identify. I may get lucky at the National Archives one day and see the original design.
This has also been auctioned as a lamp holder at some point.
If you have any more details on this piece, do get in touch
30/10/2019 – This site suggests that it is a Tretchikoff?
Also found it in September 2021 available in brown lacquer
