The organ was originally built by the Hutchings firm of Boston as their Opus 1640 in 1908. The organ was extensively modified in 1962 by Welte-Whalon of Portsmouth, RI.
The 1987 work included a new 3-manual Austin console drawknob console and extensions of two reed ranks. Messrs. Czelusniak et Dugal, Inc. who maintain the instrument have done additional tonal work. Two electronic 32-foot stops were added by the Walker Technical Company of Zionsville, Pennsylvania. And in honor of Pomfret School’s Centennial Year, a Festival Trumpet was added in 1993. This stop, modeled after the Harrison festival trumpet at All Saints’ Church, Worcester, Massachusetts, was built by David Broome at The Austin Organ Company.
