Sometime between 1941 and 1943, as my father's ship, HMCS St. Laurent sailed near the Canadian East Coast, Douglas Digby 757 flew over the convoy his destroyer was escorting. The ship's photographer took this picture and I inherited it when Dad passed away in 2005. The photo I have is about 1.5 inch by 2 inch in size. I managed to blow it up enough to see the number.
