I found this link, which will give you an idea of the content etc, but it is a little more expensive buying from here
Aside from this book, what others mainly feature the memoirs of tank/armoured car crew from the First World War? Those i've already read are mainly about the development, i'm currently reading "The Devil's Chariots" which seems to mostly be about the problems of development and production, and it's a great cure for insomnia!
Another book is "A Company of Tanks" by Maj. W. H. L. Watson. Out of print but available as a pdf (15Mb) at the internet archive. If the size is a little large, I typed up a version which comes in at 1.5 Mb here.
