This medal is one of the Stars for the British Army in the First World War. It may have been the 1914+ Star or the 1915 Star or variation. To qualify the recipient would have need to have been serving in an active theatre of war between specific dates - dependent upon the particular star. If the recipient was still alive at the end of the war, then he would also have received the British War Medal and the Victory Medal.
