Steingraeber factory pictures, bridge agraffes & adjustable vertical hitchpins

[Kazuo Yoshizaki]

This was what I heard from a piano tuner in Paris who asked Mr. Paulello
about it. There may be something lost in translation, but I just assume
anything that adds stress to the board inhibits the movement of the board.
If you have no downbearing, no mass and no tension sideways, the board moves
more freely, doesn't it? (Of course that is not realistic.)
