life After the Second World War Allingham continued to work for Ford until he retired in 1961. After Denis Goodwin of the First World War Veterans' Association tracked him down in 2001, Allingham took a prominent role in telling his story so that later generations would not forget. On 16 October 2003, he helped launch the 2003 Royal British Legion Poppy Appeal with model Nell McAndrew aboard the cruiser . He was quoted as saying "[The veterans] have given all they have got for the country ... I owe them ... we all owe them." A ceremony at The Cenotaph in Whitehall, London on 4 August 2004, marked the 90th anniversary of Britain's entry into the First World War. Allingham attended, together with three other First World War veterans, William Stone, Fred Lloyd and John Oborne. Allingham also marched past the Cenotaph on Remembrance Sunday in 2005 and laid wreaths at memorials in Saint-Omer on Armistice Day. That was the last time a First World War veteran marched past the Cenotaph and it marked the end of an era. No First World War veterans were present at the Cenotaph for the 2006 Remembrance Sunday Parade. As the last surviving member of the RNAS, and the last living founding member of the RAF, Allingham was an honoured guest when the British Air Services Memorial was unveiled at Saint-Omer on 11 September 2004. During the ceremony, Allingham was given the Gold Medal of Saint-Omer, which marked the award of the Freedom of the Town. The group of RAF technical trainees that joined him at this ceremony continued to visit Allingham at his retirement home in Eastbourne. In November 2005 Allingham accepted an invitation from the International Holographic Portrait Archive to have his holographic portrait taken. His image was recorded for posterity in December 2005. At the same time, an exhibition was being planned for London's floating naval museum on board HMS Belfast, entitled the Ghosts of Jutland. A copy of this portrait was donated to the museum and the Duchess of Gloucester unveiled the portrait to mark the opening of the exhibition. Allingham was awarded the freedom of his home town of Eastbourne by the mayor on 21 April 2006. He lived on his own until May 2006 when, one month before his 110th birthday and with failing eyesight, he moved to Blind Veterans UK (formally known as St Dunstan's), a charity
