Updated through online information from James R. Stettner. -- The organ was originally built for the National AGO Convention held in Seattle in 1970. It was relocated shortly thereafter to Blessed Sacrament by Balcom and Vaughan, who were the builder's reps at the time. Sometime after its installation, Balcom and Vaughan added a 16' Subbass of 32 pipes (all metal) on an E-P chest. This increased the size to 5 registers, 9 speaking stops, 5 ranks, and 256 pipes.
Altered Balcom & Vaughan.
