Hugh White Studios information request - COPYRIGHT HOLDER?

[Barney Monk]

Hi there, 

I'm hoping someone out there may be able to help me out!

I'm trying to track down the current copyright holder for work completed by Hugh White Studios.

I believe they have now dissolved but they were located at 6 Cavendish Street London from 1939 until at least 1950. 

If anyone has any information regarding the Studio, I would be incredibly grateful.

Many thanks,

Barney
