Excellent, you've read Astbury's book. I checked the UK site of Amazon and it has it. But mustn't be readily available "usually dispatched within 3 to 5 weeks."

Hopefully it should be worth the wait. I read reviews on it somewhere and it has some good praise. I think Astbury's research was mostly from newspapers too. The fact that it was wrote in the 20's shouldn't be too much of a factor should it?
