Updated through online information from Tom Bailey. -- This organ and the other listing for the Roosevelt at St. Peter's are the same instrument. When the church moved, the Catholics bought the building. I have the contract for which James Campbell (and a young Ted Gilbert, still alive) rebuilt the organ in the 1940s. The above explanation is the best I have seen as to the current whereabouts of the instrument. It was probably destroyed when the building was razed in the 1970s.
Identifed through information posted to PipeChat October 3, 2008 by Allan Remsen: Relocated and rebuilt Hilborne Roosevelt [sic. Hilborne died 1886, it was Frank Roosevelt/Roosevelt Organ Works -ed.] organ of 1889. "The organ was rebuilt and moved into the auditorium at St. Patrick's Church in Bay Shore. I heard it once, and it was a very distinguished sound. The last time I was in the building, the console had been removed, and the pipe chamber was being used as a store room. The pipework and chests were still there. I have no idea what has become of it since I last saw it."
