A friend sent me this image, I have shown it to all of my family, and we agree it's our dad, second from the right, in New Guinea with his Regiment. (lower image)
He was a 'gunner' with the 25 Pounders, (the size of the shell) and in later years wrote the official biography of the war and his Regiment. It was a huge book!
