In November 1926, the Irish Defence Forces decided upon adopting the German "Stahlhelm". However when the Irish government contacted German Foreign Office with a request for a sample they were informed that Germany was barred from exporting steel helmets by the Treaty of Versailles. The Irish then turned to London based Vickers, ordering 5,000 copies of a model closely resembling the M1918 helmet. The helmet remained in use until it was replaced by the British Mark II model in 1940. Following the outbreak of World War II, the helmets became the subject of anti-Irish propaganda originating in Britain. A large number of the withdrawn helmets were reissued to various emergency services after being painted white.
