  • Identified through online information from Randolph Blakeman. -- In conjunction with a restoration of the sanctuary, the organ was further renovated by the Kegg Organ Company. A second Diapason was added to the Great, the Scharf in the Swell was removed and a Vox Humana was added, the Choir Trumpet was replaced by a Cornopean, and the Pedal Bombarde unit was replaced by a Trombone unit. One of the Great Diapasons is now on display and has been stenciled to look like the display pipes of the original organ from the 1880s (builder unknown). The original organ was replaced in 1919 by a three manual Austin, which was replaced in 1959 by another three manual Austin. The present Austin organ has had many additions over the years (the previous organist told me that the Choir was originally just a collection of flutes, though I am guessing that the Clarinet was also original). The organ now has, according to the new organist, 52 ranks of pipes. (Database Manager. February 6, 2013)
