Looks like a great idea to me. I always wondered why Baldwins small balance rail screws for raising or lower their balance rails never caught on either. I liked that system. Swift and simple.

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. Willem (Wim) Blees, RPT Piano Tuner/Technician 94-505 Kealakaa Str.
