Now I was brought up in England by Irish parents. I spent most of my holidays in a small seaside town just south of Dublin with my Grandparents. My Grandfather was an avid reader and this was passed on. Anyway I found a number of books in my Mum's attic, the above being one of them. There is another about Cork's story and there may be others.
The point I'm getting to is that the tales within these pages are a veritable mine of information for VBCW, and at a stretch zombie gaming. Living off the land, ambushing the enemy (whether they be bands of gangers or organised enemy). Limited food, ammunition and surviving on your wits.
It's not a great piece of literature but it is written by educated people who know how the English language works and it has a great deal of charm in that respect.
If you are interested in the inter-war period and the VCBW ethos it's well worth attempting to get hold of from your library. I would suggest an internet book stall but then I saw the price that was being asked!
Good luck out there. Note to self 'get a bloody zombie game done!!"
