Updated by Roger Meers, who has heard or played the organ.
I saw the organ 11/21/2017. The switching has again been revised. The original prepared Swell Tierce drawknob is now Pedal 16- Trumpet on Swell. The original Positiv 4' drawknob is now Great 8- Trompeta on Swell. The change of Pedal 4- Quintade to 32- Resultant remains.
Updated through online information from Joe O'Donnell. -- I saw the organ in early 2009. The switching has been revised to provide a 32' resultant in place of the Pedal 4' Quintade and to allow the Trompeta Real to play on the Swell (using the prepared Tierce drawknob).
Updated through online information from Jeff Scofield.
Identified through online information from James R. Stettner. -- Möller originally proposed the organ on May 21, 1964. It was later revised on June 16, 1966 before the church signed the contract. The Great 8' Trompete Real has brass+copper resonators. I had access to the Möller proposal and examined the extant organ June 30, 1993.
