Besides being ultra quiet, the operation of the cards rising is very smooth. The houlette is of smooth finish heavy plex into which the cards fit perfectly. The deck is completely self contained including the winding mechanism as well.
The activation is by a tiny tab at the top of the deck which is moved 5/8" of an inch to begin the rise. The Jon Martin feature is of the pressure plate which holds the cards against the motive action to bring up the cards.
The effect also comes with a 3-Way Forcing Deck separate of the Mechanical Pack. This is a quality item from many years ago. Condition very fine.
