From the NYC AGO NYC Organ Project: The organ in Our Saviour's Atonement Lutheran Church was originally built by M.P. Möller as Op. 9370 (1960) who installed it in the gallery of the Chapel of the Interchurch Center on Riverside Drive. In 1982, the organ was reconfigured by Austin Organs, who added several ranks of new pipes and provided a new three-manual rocker-tab console. In 2007, prior to the installation of a new Klais organ, the Interchurch Center donated the Möller/Austin organ to Our Saviour's Atonement Lutheran Church and provided funding for its removal. Glück Pipe Organs of New York City was contracted to move the organ, set up the Great division and connect the resources of the previous Möller organ (Op. 5623) to the Austin console. The remainder of the Interchurch Center organ is being installed in stages by Mann & Trupiano of Brooklyn as funding becomes available. Following is the proposed specification (as of 2011) for the reconfigured organ.
