I eyeballed a copy in the Studies Library and my initial thought was that it was a bit of a jigsaw of Bawden's report as well as some of the usual photographs. It was also a bit thin.
However, for £4.99, it is exceedingly good value indeed. I will have a copy for that price.
I'd like to see a reprint of "The Great County Adit" by Buckley as I know several people looking for copies and my copy is a collection of pages.
