So What Do They Race in Mono?    Mono-Display-Board---Classes-Final

I was leaning on the pit wall at Snett when a bloke asked me this very question. As a lifelong motorsport enthusiast, but not a Mono insider, I had a vague idea, but wasn't sure of the detail, so I thought I'd look it up and try to summarise it for my own satisfaction. Also, the Asst. Ed. thought it wasn't a bad idea to get an outsider's perpective on this. So, after a trawl through the  Regulations and "Startline" here it is.
