Grainy Library of Congress reference copy of contact sheet chronicling Scott demonstrating one of his electronic gizmos to then-wife, singer Dorothy Collins, at their Long Island home. Year unknown, but likely mid-1950s. Judging from the slanted ceiling, the monstrous machine appears to be installed in their attic. Whether it was built or hauled up there is an intriguing question. The device could be an early version of the Electronium, Scott's "instantaneous composition-performance machine" which he developed in the 1960s. Whatever it is, the magnificent instrument no longer exists.

I included another (presumably earlier) version of this device on page 23 of the book accompanying the Manhattan Research CDs. Same room, same piano bench, same shirt & haircut. I have another pic of this instrument, but neither RS nor DC are in the frame. I've been hoping that sooner or later we'd find a photo of this device with some info written on the back, or a caption in an old magazine that would explain more detail, but I've had no luck in that department. Yet.
