Updated through online information from Randolph Blakeman. -- I was a college student singing in the St. Andrew's choir when the Great Trumpet was added and also took some organ lessons on this instrument, so I remember the original stoplist well, and there was a Mixture IV in the Pedal which is not listed. The organist at the time, Dr. John Paul told me that it started at 1 1/3' pitch for greater contrapuntal independence.
Identified 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:
