Looks like it might be the source of that old wives' tale (concerning hammer technique for tuning) about lifting the pin in its elongated slot, and then setting it. I wonder how many schemes there were to avoid the wooden pinblock. The Mason screw-stringer is one, and Broadwood had one that I have seen described but without diagram.
