When restored by A. Richard Strauss of Ithaca, New York in the 1990s, he found the signature of Phelps inside the organ. Phelps was central upstate New York's first organbuilder (active ca. 1815- ca. 1850), and there are contemporary references to him that suggest he was self-taught. His building activities have been noted in several communities, but primarily in Guilford, New York.
