Coupler Gt. & Sw.      Swell to Great 

(1) Replaces the 1874 Johnson Melodia 8', itself a replacement of the original St. Diapason Treble. 
       Following Johnson practice, the new pipes are an identical copy of the Swell Stopped Diapason. 
(2) Common metal bells on zinc stems, tapered shallots with reverse-bevel shallot bottoms,
       atypical tuning wire and block design, common metal boots.
(3) Added by Wm. A. Johnson behind the Great walkboard, using the Bellows Signal stop action,
       with its original label found under the organ in 2012 and restored to place.
(4) The organ was begun as a G-compass instrument, and altered prior to its installation to C-compass,
       as evidenced by the Great and Pedal windchests, and Pedal pipework. The Pedal pipes were built
       prior to the organ's conversion as a unison open wood Diapason from 10 2/3' G, 13 pipes, shortened
       and rebuilt as a C-compass 16' Sub Bass, but retaining the original pitch markings, resulting
       in this stop being an unusually large scale for a Pedal Bourdon. Dated newspaper shims indicate
       the organ was begun at least as early as 1849.
