Many of Ough's models are on display or held in store in museums including the Imperial War Museum, the National Maritime Museum and the Royal United Services Museum. One of his earlier models was of the battleship HMS Queen Elizabeth, which he made for Lord Howe, who presented it to Earl Beatty. There followed commissions for his models from many museums. At one time he was employed by Earl Mountbatten to make models of ships on which he had served, who remarked in a reply dated 20 July 1979 to a letter received from a visitor to his Broadlands estate "How interesting that the great model maker, Norman Ough, was a cousin of yours... I was told by the maker of the model of HMS Hampshire, also on display, that other model makers considered Norman Ough, the greatest master of his craft of this century."
