Updated through online information from Richard C Greene.
Update from Larry Wheelock: "Echo division added by Austin Organs Inc. in 1948 as Op. 1628-A. Substantial changes to stoplist in '60's and 70's by Austin and a local builder, including removal of shades from GT and replacement of a heavy velvet curtain with a more sound-transparent material. The GT Mixture stands on the chest but the SW and CH mixtures are on free-standing DE chests within the divisions. Some Pedal upperwork is on EP chest of unknown origin. Substantial finishing and re-voicing by Michael J. O'Dea in 1996."
