Identified through online information from Thomas Brown. -- The organ received a new Peterson 99-level combination action in 2003. It also received a revised Swell Mixture that year, lowering the pitch of the stop from a Zimbel-type mixture to a lower-pitched, more usable mixture. In 2010, the Swell 4' Flute Ouverte, which always suffered from serious tuning problems due to its scale and reaction to its placement on the chest, was replaced by a more narrow 4' Flute harmonique. Finally, the Swell 16' Basson stop was converted from a half-length stop throughout to a full-length stop, beginning at note 15. Sometime in the mid-1980s, two Walker digital 32' stops were added to the organ. Otherwise, no changes have been made to the instrument's voicing.
