This medal was awarded to my friend, Dick Robinson's Great Aunt, who served as a Nursing Sister on the front lines of France from 1915 to 1919. They have no idea where it is from and what it signifies, or even if it is an official medal.
She was a member of the Queen Alexandra's Imperial Military Nursing Service Reserve, and she was also awarded the Military OBE, the Royal Red Cross First Class, the 1914 Star, British War Medal 1914-1918, the Victory Medal 1914-1918 and the Medaille de la Reine Elisabeth.
My friend has published her diaries on the Internet, and some of you may be interested to read them here: Edith Appleton.
If anyone knows what the mystery medal is, please could you let me or Dick know? Dick's contact details are on the Edith Appleton website.
