In March 2013, after two years of in-depth trace analysis by The Forensic Science Service on behalf of auctioneers Henry Aldridge & Son, and seven years of evidence-gathering by the Wiltshire-based auction house, it was announced that a violin found in a British man's attic inside a leather case with the initials "W. H. H." was the instrument used by Hartley during the ship's last moments. The identification was helped by an engraving on the German-made violin which his fiancée (Maria Robinson) had placed on the instrument in 1910 which read: 'For Wallace on the occasion of our engagement from Maria.' Further tests by a silver expert from the Gemological Association of Great Britain confirmed that the plate on the base of the violin was original and that the metal engraving done on behalf of Maria Robinson was contemporary with those made in 1910. A CT scan enabled experts to view 3D images of the inside of the violin. The fine detail of the scan meant experts could examine the construction, interior and the glue holding the instrument together showing signs of possible restoration. While researching the origins of the violin, the auctioneers Henry Aldridge & Son and Christian Tennyson-Ekeberg, biographer of Wallace Hartley and author of "Nearer, Our God, to Thee: The Biography of the Titanic Bandmaster", discovered the transcript of a telegram sent to the Provincial Secretary of Nova Scotia, Canada, dated 19 July 1912 in the diary of Hartley's grieving fiancée, Ms. Robinson, in which she stated:
The Hartley violin was exhibited in Northern Ireland at the shipyard where the RMS Titanic was built, Titanic Belfast, and in the United States at Titanic Branson and Titanic Pigeon Forge museums. It was sold by auction house Henry Aldridge & Son in Devizes, Wiltshire, England, on 19 October 2013 for £900,000 ($1.7 million US), as reported by BBC, NBC, and The Washington Post.
