For security reasons during World War 2 all Royal Navy sailors and Wrens wore just H.M.S on their cap tally. The name of the ship was omitted.
This Wren also wears a pair of crossed signal flags on her right sleeve indicating that she is a Visual Signaller.She would have been capable of sending and receiving messages from shore to ship and vice versa.Wrens did not go to sea.
During hours of darkness this would have been by morse code using an Aldiss lamp.
