Updated by Edwin H Myers Jr, who gave this as the source of the information: I have a number of Estey pipes from this organ. I picked up a number of Estey pipes from a residence some years back that were marked 1147. There were no complete sets but the woman told me her husband had other pipes years ago. The church no longer exists and It would seem the organ pipes at least were "parted out" but nothing else.
Identified by James R. Stettner through information from the Estey Opus List, published in The Boston Organ Club newsletter, 1973-1979.
