This three-manual instrument, with electro-pneumatic action, was originally installed in the Holy Name of Jesus Church by the Estey Organ Corporation in 1938. Opus numbers, stamped on the pipework, indicate that most of the pipework was originally made for an organ built by Estey (opus 1914) in 1921 for the Pennsylvania Hotel in New York City. Opus numbers on some of the other pipework indicate it was made by Estey (opus 3048) for Grace Presbyterian Church in Camden in 1933. The organ originally contained thirty-one ranks of pipes, approximately 1782 pipes.
Estey began as a manufacturer of reed organs (harmoniums) in 1852, and later (1901-1960) expanded into making pipe organs.
