Not sure if anyone is interested but this book seems ridiculously cheap to me - not my area of collecting but in case anyone is interested it is on Ebay Aus. (I am not selling it - I just saw it and thought someone may be interested) Sorry if I have posted it in the wrong place - wasn't sure where to put it.
