Wookey Hole has "An American Execution" which depicts a man in an electric chair. As I recall, not much seems to happen other than that a light-bulb in the culprit's head is illuminated after a short delay; and also a machine depicting an execution by hanging, in which the figure is dropped through a trap door. I can't remember the name of this machine.
I heard that when Walker took it over, anything left was taken down the tip accompanied with secruity to make sure it ended there. This was told to me by one of the guards as I was buying a Roman Head and an Extraordinary off him.
