Mum and Auntie Kath's wartime service

My mother Marjorie and her older sister Kathleen joined the Women's Auxiliary Air Force (WAAF) as cooks in coastal command airbases. Places my Mum mentioned were RAF Chivenor, near Barnstaple, Haverfordwest West, Plymouth, and at some point they must have been in Morecambe where the street photographer took the snap of them.
