Updated through online information from Samuel Baker: It’s a shame the couplers are not listed. Holtkamp would not duplex the clarinet stop from the Skinner Solo division onto the Positiv but agreed to include a Clarinet to Positiv coupler. Surely unique.

From the NYC AGO NYC Organ Project: Under the leadership of Vernon de Tar, Organist and Choirmaster from 1939-1981, a new organ was built in 1967 by the Holtkamp Organ Company of Cleveland, Ohio. At Mr. de Tar's insistence, Holtkamp provided a fourth manual for a Solo division that incorporated selected ranks from the previous Ernest M. Skinner Organ, Opus 860 (1931), although the Skinner reeds were revoiced to play on lower pressure. The retained Skinner ranks were from the Solo (Flauto Dolce, Flute Celeste, English Horn, French Horn and Orchestral Oboe), Swell (Vox Humana) and Choir: (Clarinet).

Holtkamp installed the organ on both sides of the chancel. To the left of the chancel were exposed pipes of the Great, Positiv and Pedal divisions, behind which was the enclosed Swell division. On the opposite side of the chancel was a chamber for the enclosed Solo division, the tonal opening of which was masked by a façade. The detached four-manual stop-key console was on a raised platform between the choir stalls and pulpit, allowing the organist to direct and hear the divided choir.

The organ was dedicated at the 11am Morning Prayer service on Sunday, January 15, 1967. In lieu of the usual sermon, Vernon de Tar played a "sermon in music" – organ works from many centuries and nationalities – and the choir sang grand anthems. One week later, Mr. de Tar played the dedicatory concert. In the next months several great organists were heard in recitals, including Robert Baker, André Marchal, Charles Krigbaum, Jack Hennigan, Marilyn Mason and Leonard Raver.

After 43 years of service, the Holtkamp organ was used for the last time on Sunday, December 27, 2009. The organ was sold to a family for their Oregon residence.
