Turkish Half Moon "Gallipoli Star" (Eiserner Halbmond/Gallipoli Stern). The award was known as the Ottoman War Medal (Turkish: Harp Madalyası) or the Iron Crescent (Eiserner Halbmond). It was instituted by the Sultan Mehmed Reshad V on 1 March 1915 for gallantry in battle. This decoration was awarded for the duration of World War I. It features a five-pointed red enamelled star with a raised crescent design, inside the crescent is the tughra (cipher of the Sultan). The star is made of silver, there are a few very small enamel cracks, see photos. The star is not visible maker marked, but can very likely be attributed to the company of 'Meybauer' from Berlin. De details on this star are simply stunning. Nice original piece!
