I can confirm that the panels in Malmason were the ones from Staffordshire which I photographed in the 1990s.
They were removed from the Home just prior to its demolition in 1974 and were given away as they were difficult to use, odd corner panels.
They were used to create a very attractive shop counter.
The owner sold them by auction to an interior designer when he retired in 2006.
The designer installed them at Malmason.
My investigation has lead me to locate another two panels in Portsmouth.
