The photo was published in the Dutch magazine De Prins dated 1 June 1912 page 254 when King George V sighted on board of the British naval manoevres off Weymouth. The Dutch magazine called her Neptunus but this must be the dreadnought HMS Neptune, ordered in 1908, laid down at the Portsmouth dockyard on 19 January 1909, launched on 30 September 1909, commissioned on 11 January 1911 and finally broken up in September 1922. She served as the flagship of the British Home Fleet between May 1911 and May 1912.
