Identified through information in Unpublished Organ Research Notes of Dr. Stephen Schnurr; as edited by Joseph McCabe, 2008: Alterations and additions to Votteler-Hettche rebuild of relocated Ryder organ of 1874. In 1923, the Antiphonal division (playable from Great and Choir) was installed in the northeast corner of the rear balcony by Votteler-Holtkamp-Sparling, opus 1383. This division was placed on electro-pneumatic action. By the mid-1930-s mechanical problems began to surface in the organ. A letter from Walter Holtkamp, March 30, 1934, indicates that the Great 8- Trumpet "is in very bad condition and practically beyond repair�. He recommended replacing it with a 2-2/3- Nazard (Nachthorn) for $137.00, as "this change is in line with the policy of gradually but permanently modernizing and replacing the worn out parts of the organ.� The church accepted this proposal on April 6. Also at this time, slide tuners were fitted to the metal flue pipes at a cost of $548.00.
