I've got a spare copy of the Police Riders handbook (aka the blue book) if anyone wants it. Its the book the Police use for their training and is the basis for most/all advanced riding. (collection from Westbury)
I think I bought one and got a free copy when I signed up with RoSPA? Its quite good to read especially if you are planning on doing some advanced training, although the IAM book you get when you sign up with them is much better
