From the NYC AGO NYC Organ Project: The contract (Nov. 5, 1947) shows that J.H. & C.S. Odell was contracted to rebuild and enlarge the previous organ, Odell's Op. 147, at a cost of $12,500. This organ was described in the December 1948 issue of The Diapason:

The organ is a gift of Jeremiah Rutger Van Brunt, descendant of one of the founders of New Utrecht in 1657, in memory of his wife, Anna Gertrude Remsen Van Brunt, and replaces a two-manual tracker instrument installed by J.H. & C.S. Odell in 1875. Most of the old pipes have been used in the rebuilding and enlarging project. Mr. Van Brunt, 81 years old, recalls that as a boy of 8 he was the first to hear the old organ played by the men making the installation while he was at work in his grandfather's onion field.
The specifications for the instrument were prepared by William H. Odell in collaboration with Ethel Watson Usher, director of music, and the Rev. Martin Paul Luther, M.A., pastor of the church. George J. Grathwohl of the Odell Company supervised the installation.
