Identified through online information from James R. Stettner. -- This was a mechanical restoration with tonal changes. The original 27-note flat/parallel pedalboard was replaced with a 32-note, concave/radiating one. Several tonal changes were made to both the Great and the Swell. And the Pedal division was enlarged to 4 independent registers on E-P unit action, unified to play as 8 speaking stops. The Swell to Great 4' coupler is still actuated by a hitch-down pedal, and the four fixed, mechanical foot trundles for Piano Great, Forte Great, Piano Swell, Forte Swell were retained.
