Church Council, by the evangelical Sir Charles King-Harman. A number of such cases, including the purchase of the advowsons of Clapham and Hampstead Parish Churches by Sir Charles, led to the passage of the Benefices (Purchase of Rights of Patronage) Measure 1933. This allowed the parishioners of St Magnus to purchase the advowson from Sir Charles King-Harman for £1,300 in 1934 and transfer it to the Patronage Board. St Magnus was one of the churches that held special services before the opening of the second Anglo-Catholic Congress in 1923. Fynes-Clinton was the first incumbent to hold lunchtime services for City workers. Pathé News filmed the Palm Sunday procession at St Magnus in 1935. In The Towers of Trebizond, the novel by Rose Macauley published in 1956, Fr Chantry-Pigg's church is described as being several feet higher than St Mary's, Bourne Street and some inches above even St Magnus the Martyr. In July 1937 Fr Fynes-Clinton, with two members of his congregation, travelled to Kirkwall to be present at the 800th anniversary celebrations of St Magnus Cathedral, Kirkwall. During their stay they visited Egilsay and were shown the spot where St Magnus had been slain. Later Fynes-Clinton was present at a service held at the roofless church of St Magnus on Egilsay, where he suggested to his host Mr Fryer, the minister of the Cathedral, that the congregations of Kirkwall and London should unite to erect a permanent stone memorial on the traditional site where Earl Magnus had been murdered. In 1938 a cairn was built of local stone on Egilsay. It stands 12 feet high and is 6 feet broad at its base. The memorial was dedicated on 7 September 1938 and a bronze inscription on the monument reads "erected by the Rector and Congregation of St Magnus the Martyr by London Bridge and the Minister and Congregation of St Magnus Cathedral, Kirkwall to commemorate the traditional spot where Earl Magnus was slain, AD circa 1116 and to commemorate the Octocentenary of St Magnus Cathedral 1937".
