I notice in the pictures that the action rails and the key-bed rails are mounted to the plate. Looks like a very stable configuration regulation wise. Problem with most uprights today is that the key-bed and therefore the action moves with the weather. Lothar Schell has a similar innovation in that the action and the back rail are mounted to the plate. The two front ones still move with the weather, arguably to little effect with the back of the keys stabilized. It look like the Rippen was a piano with potential. Other than the old plastic parts, everything looks good. Plastic, or was that Carbon Fiber, is making a come-back nowadays. ;-) Andrew
