Whew! That was a disgusting job. Anyway, now the keyboard is clean and I can point out some details. As I said before, this is an electromechanical console. That means that both the organist's force and electricity are used to control the instrument. (As opposed to the all-organist or mechanical action of the Stone Church organ that we are working on.)The fulcrum of the keys is the red and black dots in the center. The return springs are just visible next to the metal bar at the back. Underneath the metal bar are little levers that the keys push up. That moves a contactor bar under the white area to touch one or more metal leads. If a circuit is completed, a note sounds, if not-well, it doesn't. There are one or two other things going on under the white bars, but without clear pictures it is impossible to really explain. Trust me, it works.
