Updated through information adapted from E. M. Skinner/Aeolian-Skinner Opus List, by Sand Lawn and Allen Kinzey (Organ Historical Society, 1997), and included here through the kind permission of Sand Lawn:
Electrification of 1872 J. H. Willcox. Replaced by Aeolian-Skinner Opus 1240 (1951).
Identified through on-line information from James R. Stettner. -- This was reportedly a rebuild and electrification of the existing 1872 J.H. Willcox instrument. The organ seems to have remained in the same chamber, but the chancel side has been opened-up and a facade is visible there.
