My grandfather Herbert Dent served in the Durham Light Infantry Home Guard from 1940 to 1945. He’s on the front row, 3rd from left on the first photograph, 2nd row, 5th from left on the second photograph and front row, 4th from left on the third.
The photographs would have been taken between 1943 and 1945 when Herbert became a Sergeant.
