The Red Cross and St John Ambulance assist people around the world.
Now, they have assisted the Northern Advocate in solving the mystery of a wartime photograph published in Saturday's paper.
The photograph, published again today, shows a group of women clustered around a vehicle, tools in hand, circa 1939.
On Saturday, I hypothesised that the group was part of the Women's Land Army, later know as the Women's Land Service, who undertook agricultural jobs while men were away fighting in World War II. Close, but not quite true.
The women are members of the Northland Red Cross Transport Division who manned the Whangarei ambulance station during the war, and drove the ambulances. As part of their training, the division was required to have some mechanical knowledge and this photograph depicts a maintenance session which took place on a 1926-27 Model T Ford at Whangarei Engineering Company (later known as Hatea Motors) in Walton St.
