The rebuilt Roosevelt/Skinner/Moller organ was replaced by the Schlicker Organ Co. with a large and completely new 3-manual organ in 1975. To my knowledge, no parts of the old organ were recycled.
Identified through information adapted from E. M. Skinner/Aeolian-Skinner Opus List, by Sand Lawn and Allen Kinzey (Organ Historical Society, 1997), and included here through the kind permission of Sand Lawn:
Reusing 10 existing ranks and 11 extra façade pipes. Rebuilt by M. P. Möller, #R-579 with twenty-seven new ranks in 1957.
