I believe this instrument to be a reworking of the Hillgreen, Lane & Co Opus 859 (ID 63278) that was originally built for this building in March 1926.
Updated by Tate Ashby, who has heard or played the organ.
Unfortunately, this organ was removed and the entire building demolished some time during 2016. The parts were locked into storage, scattered amongst workers, or destroyed entirely, to the best of my knowledge.
