"They looked too good to be left floating around, or go to the dump," he said, "but there was no hope of finding who had owned them, so I put them in a safe place. Then I saw the story about what had happened to Rex's books."
Mr and Mrs Matthews were thrilled almost beyond words to receive the books, and last week they travelled north from Hokitika, where they have lived for the last 45 years, to thank Mr and Mrs Lay.
They also gave them a large piece of greenstone, which had been given to them by a veteran of Victor II Company, to pass on, and two greenstone pendants.
And the books would be very carefully looked after, Mrs Matthews said.
"An ex-army friend was looking at them and asked if he could borrow them," she said.
"I told him hell no, he was out of luck. He can come to our place every day and read them if he wants to, but they're not leaving the house."
