Hi Simon!
I'm currently reading Arthur Hawkey's book on Sir Hiram Maxim - For those not in the know he's that amazing guy who built amongst other things The Flying Machine at Blackpool (105 years old this year and still flying).
I also bought from Joyland Adrian Fisher's Mazes and Labyrinths recently which is a nice little read.
I have RCCGB's White Knuckle video which I still watch and I also refer to the hardback version of A Century of Fun for most things PBB.
Riding on Rainbows was a detailed read and I was made up to see that my website themagiceye was referenced on several occasions so I would have to plug that!
Can't help with the Charles Wicksteed book though. Good luck with finding a copy.
Gary
