You do find interesting things in holes sometimes!
William Walker is currently rather involved with the new Isle of Wight Studio just now, I think.
You might reach him there.
I'm sure he'd be happy to confirm or deny his work
I did bump into him at a fair, a couple of years ago, along with Richard Harris, but didn't get to chat, he was so busy.
Origninally, he had worked at IoWSG, and takes credit, (along with Michael Harris), for the innovation of Azurene and the subsequent design award given to the studio for that.
Not that I found William Walker in a hole!
But I did help him resize his image.
