Updated through online information from John Igoe. -- Opus 947 would have been built in 1879. This date is corroborated by recent article "Lynnwood Farnam on American Organs" (The Tracker (Fall 2014). Farnam is quoted as saying, "There is a very ancient and clumsy device (out of order) for effecting a crescendo and diminuendo by bringing on and off stops in sequence. It is a long studded iron strip placed above the pedal board under the com. peds. By moving it to the right a crescendo is effected & by moving it to the left a diminuendo. There is an indicator above the Sw. keys for this accessory. The stops of the Gt. are arranged in the opposite of the generally constructed way, having the trumpet & mixture at the bottom & the diapasons at the top tier."

Central Congregational merged with 1st Presbyterian in 1932 to become Church of the Covenant.
