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.

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.
