One would first assume this was made by Taytelbaum by the quality and overall appearance but it is not.  Making use of a 1 Guilder Coin the rod is placed in the center hole of the vertical upright and the coin is dropped in the top opening and passage cannot happen because of the rod.  The coin is dropped back out and rod shown again and then replaced back in the hole.  The coin is dropped in once more and the rod is given a few twists and the coin drops completely through to the bottom where it is seen in the opening below!  Beautifully made in plex with Engraving standing 3 3/4" high.  Condition First Rate.
