A 4 1/4" cube made of wood is shown and a cover with no top or bottom is sleeved over and this is placed upon an elevated base. A tube of metal is placed upon the top of the covered block and tapped down into the cube. The square cover is lifted away showing its empty condition. All that remains is the tube setting upon the elevated base. The tube is lifted and within is a solid wooden ball of the same color and stripe design as the wooden cube seen at the beginning!
A croquet type mallet is shown in the illustrations but instead a plastic handle tapping device is used. The condition of this nicely finished wood apparatus is First Rate. From 1984 and includes 2 pages of illustrated instructions.
