Puzzle Details

This is one of a series of can shaped sliding puzzles with the layout of a 7Up lemonade can.
It comes from the collection of Dieter Gebhardt.

While the pieces are quite stiff and can only be moved with effort and loss of fingernails, it helps a lot to lube it with silicone.

To my surprise this puzzle can have - different to typical 2D sliding puzzles have a parity problem, having the last two pieces exchanged.

Size: Can height 10.7cm, diameter 6.4.
the rhombic sliding pieces have an edge length of 1.9cm
