Cursory survey work reveals an enormous amalgamation of recycled and new material by a plethora of builders including Welte-Mignon, The Aeolian-Skinner Organ Company, E.M. Skinner & Son, Hook & Hastings, The Aeolian Company, Dennison Organ Pipe Co., and a host of others.
Installation dates on chests suggest that the first parts of the organ were installed in 1941, using Welte-Mignon Op. 253 (St. Andrew's Methodist, NYC) as a mechanical and tonal nucleus. Aeolian-Skinner was conctracted to provide three mixtures and an 8' Bourdon for the Great in the summer of 1941 (Opus 1028). These new pipes were fitted to existing chestwork, which were shipped back to the Aeolian-Skinner factory for modification. Work was completed at a cost of $1300.00.
At what was virtually the same time, E.M. Skinner & Son was engaged to provide a sizable Solo department (E.M. Skinner & Son Op. 538). Hammond would again engage Aeolian-Skinner in the summer of 1944 to provide a new VI Cornet. These pipes were racked onto existing Aeolian Co. chests already in Hammond's possesion, and installed in the rear gallery of the castle. Hammond had conceived of this as a single stop, with each rank afforded its own dynamic expression by what was apparently a very complciated mechanism. No trace of this mechanism remains today.
The apparent remains of Aeolian Op. 1539 are jumbled into the mix, with the entirety of the "Baroque" organ being comprised of what is seemingly Op. 1539's Swell department. How Hammond came to possess some or all of Op. 1539 remains unclear, and requires further investigation.
Various changes have been made to the organ over the decades, and it is unclear when or who made these changes. The Solo Heckelophone is no more, having been replaced by a Wurlitzer Vox Humana. Likewise, a deicdedly non-Aeolian Trumpet now resides in the Baroque organ, presumably having replaced the original Aeolian pipes.
Organ technicians have included - Tolbert Cheek Morel and Co (including Richard Nickerson) Roy Carlson Kim Bolton Richard Houghton (for SSL)
Baroque and pedal divisons (on floor behind console) are from Aeolian Op. 1539 (1925, Gladstone NJ). The Baroque division is the original Swell division from 1539.
Positiv division (in the gallery) has pipework by G. Donald Harrison, but it is placed on Aeolian chests that use an Aeolian regulator and tremulant (probably Op. 1539).
Great main pipework is Welte, Great mixtures are G. Donald Harrison. Great main chests are Welte, mixture chest is Skinner double-primary.
There have been 3 consoles for the instrument: 1. Austin with a roll player located in the gallery. Rolls sold to antique store in Essex MA years ago and dispersed. 2. Austin located on floor for Virgil Fox. 3. Kim Bolton console built in 1985 with SSL system by Dick Houghton.
Only the music rack of the first console remains. The second console is extant in the castle (stored in pieces) but the keyboards are missing.
The Great, Swell, Choir, Solo, and Reed Chorus divisions are located in the ceiling on either side of the great hall. The ceiling is made out of an acoustically transparent fabric. The Positive division is located in the gallery at one end of the great hall. The Baroque and Pedal divisons are located slightly recessed into the floor under the balcony behind the console.
There are two blowers: - Spencer Turbine 6" output with a 15hp Woods motor - Spencer Turbine 15" output with a 3hp Westinghouse motor
The Fox Horn was named for Virgil Fox as a joke. The positiv was added by G. Donard Harrison. 19 stop Solo division added by Ernest M. Skinner & Son in 1941.
First 2 consoles were built by Austin with a mechanical combination action. New 3rd console built in 1981 by Kim Bolton (then operating under the E.M. Skinner Company name) using a SSL relay.
