Hello Kevin Menzies,
I have been looking at an old "Stand to" paper and I read your letter about the POW Camp. There are 2 drawings of the camp in a book that we publish called, "Little Hell- the story of the 2/22nd Battalion and Lark Force."
They were drawn by Lt R T Tyrell. The compiler of the book Carl Johnson I believe has a collection of these drawings and I understand that until they were published the family were unaware of their existence.
So here is a little more information for you.
Kind regards, 
Owen Jenkin
