Day 172/19. A photographic request

I was volunteering today at Solent Sky aircraft museum and took a very specific telephone request.
'Can you please let me have a photograph of the Sperry Auto Pilot in your Sandringham flying boat. Also on the left side of the unit is a name and serial number plate, can I have a picture of that too?'
Happy to oblige sir, and here are the pictures I took.
