BRIGG PEOPLE ASKED TO HELP WITH RESEARCH

David Layne tells us he is still working on his blog.  Currently he is trying to get photographs of all of the prisoners in his father’s POW “Wartime Log.”  His results so far can be seen at https://wallyswar.wordpress.com/other-pows/
"As you can see I have a photograph of Ronald Colbeck," he says. "Others from your neck of the woods that I need help with are:
