County Borough Of Southport ARP Mobile First Aid Post

I have seen a few other photos of the County Borough Of Southport ARP Mobile First Aid Post but this particular image was new to me. This first aid post was constructed from a modified bus and was of quite an intricate design. I am assuming that the idea was that the bus could attend at major air raid incidents when the local first aid posts may have been overwhelmed.
