In 1878 bouwde Henry Willis & Sons een mechanisch sleepladen-orgel voor de Cathedral of Saint Mungo in Glasgow (Lanarkshire). In 1903 legde Willis een nieuwe pneumatische tractuur en kegelladen aan. In 1931 verbeterde Willis het instrument en werd de tractuur door hem geëlektrificeerd. Ook plaatste hij een nieuwe speeltafel. De elektro-pneumatische tractuur werd in 1971 vernieuwd door J.W. Walker & Sons. Ook plaatste Walker een nieuwe vrijstaande speeltafel. Tegenwoordig is de toetstractuur elektro-pneumatisch en de registertractuur elektrisch. Het pedaalklavier is radiaal concaaf.
