Rich's Puzzle Cabinet

 

 
         
 

Use a coin to turn two screw heads which hold the top down. Turning them 90 degrees frees the top, which slides back out of a false tenon joint and then up to reveal the first compartment.

 
 

 
 
 
 
Then there are two sliding side panels which slide up to expose shallow compartments in the sides of the shelf.
 
 
 
 
Pushing the spring loaded bottom of the cabinet back and pressing down at the rear, frees it and tilts it up so it can be lifted free, revealing the compartment in the base of the cabinet.
 
 
 
 
In the back of the bottom compartment, there is a button. Pushing the button releases the rear panel which opens on a concealed hinge to reveal the last compartment.
