Updated through online information from Steve Bartley.
The organ was originally built for the Jamestown Exposition. Sun Paper 12/28/1907, pg7 says that it took 10 horse drawn carts to get the organ parts to the church, and the work was being supervised by Moller's superintendent R. W.Robertson. Though the building was erected in 1889, there is no indication that there was a previous organ in use.
The building was sold to the Enon Baptist congregation in 1942, and a digital organ is in use presently. The original facade, in the gallery, is extant.
