This morning I tuned a 1924 Ludwig grand with a key leveling system I had never seen before. In each key, in front of the balance rail hole and pin is a screw that goes through the key. (see picture #1). The other on of this screw is like a capstan screw, which rests on a felt rail, which is the fulcrum of the key. (#2 and #3). The balance rail is used only to keep it from wobbling from side to side. The key height is adjusted using this screw. I've never seen a system like this. It's actually quite ingenious, and wonder why it was not accepted by other manufacturers. It did not feel any difference in how the piano played.
