Hi Paul, Even in those days the workers wanted to be able to get the action out easily, for them anyway. I would first look under the key fronts, behind the keyblocks, sideways intro the keyblocks, and under the keybed. I have seen screws installed so flush and painted the same color as the surround that they were nearly invisible until the light was just right. Look under any buttons or plugs, look FOR plugs (unlikely). It is also possible there are dowel pins somewhere. The keyslip may be removable, like an S&S but so tight it is stuck. They didn't leave instructions did they. >From behind the piano? Nah, that is too obvious. Maybe the whole keybed comes out. Lots of fun playing hide and seek. Lot os luck. Newton
