De-ruption - Dexterity Puzzle

De-ruption is a brass dexterity puzzle designed and produced by Phil Wigfield.  It is part of a limited edition series of three separate dexterity puzzles.  Only 100 have been produced of each style. Every puzzle is numbered and signed. 

Using a bit of imagination, you can see that the inside of the puzzle has the shape of a small volcano.  There are 4 rocks (balls) that you need to get back inside the volcano to clean up the mess.  There are no cunning tricks; you just need a bit of time, patience and luck.

Each puzzle is handmade using a manual mill and manual lathe, and includes an acrylic top to stop the balls from coming out.  There will be small machine marks which can't be polished out.
