In 1915 bouwde Norman & Beard een nieuw orgel met 2 orgelkassen en bronzen frontpijpen voor de Church of Saint Mark in London (Mayfair) Middlesex. In 1930 is het omgebouwd door Rushworth & Dreaper. In 1980 werd het binnenwerk overgeplaatst naar de Holy Trinity Church in Brompton. Het pedaalklavier is radiaal concaaf.
