Identified through information from Fred Shetler. -- My cousin and organist John Walker's father was pastor of this church, and his mother was the organist. He remembers it also being a H & H.
He tells me in E-mail that what story he remembers it was originally located in Falling Springs Presby Church in Chambersburb, PA before being re-located to Spring Run, PA; not sure of the date. Some years ago it was converted to electric action -- again, not real sure of the date.
That was a really niced voiced H & H & John agrees. The H & H was taken out of the church several years ago.
