As far as I know, the action that Calin has is known as a breast action, taken from the shape of the jack; it looks like a chicken breast. The graphite should be on the surface of the breast part of the jack and not on the leather. This action can be found in early Bluthners. The action that Michael G is referring to is called a French Crank or "Molyneux" action where the jack has a set off button that slides up the board. The whole board in this case is graphited. This action can be found in early Bechsteins with Schwander actions. Extremely difficult to regulate when action is worn. Needs lots of key dip to avoid hammer dither. Later versions progressed from using a flat board to a convex board to accelerate jack movement near the set off point.
