The church chose Thomas Appleton to build a three-manual 23-stop instrument, completed in 1841. According to The Musical Cabinet, October 1, 1841, it had a pine Gothic-style case, painted white. At 23'6" high, 14'6" wide, and 11' deep, it was situated in a recess in the front gallery. The organ cost $3,600.
[specification given -- see Stoplist tab]
The largest pipe is CCC, or the once-marked great C of the Germans: that is, two octaves below the Base staff. It is 16 feet long, and 18 inches square.
The compass of the manuals, or key-boards, is from GGG, (the German once-marked great G, or G an octave below the lower line of the Base staff,) to F in alt., ( the German thrice-marked f'", or F an octave above the upper line of the Treble staff.)
The compass of the pedals is an octave and a half, from C' to G.
The instrument is also furnished with Stops for coupling the Great Organ and the Swell; coupling the Choir and the Swell; coupling the Great Organ with the Pedals and the Choir; Pedals Check; and Bellows Alarm.
This second organ was sold in 1862 to Zion Church (later St. Joseph's Roman Catholic Church) in nearby Newport, RI, when the third instrument, E. & G. G. Hook Op. 314, was installed in the rear gallery.
