Puzzle - Hanayama - L6 - Enigma

Challenge Yourself with the Huzzle Level 6 Enigma

Patented in America in 1975, the somewhat swirled pieces of this puzzle by Eldon Vaughn must be disjoined and then put back together. 
I once found a smaller version of this puzzle about twenty years ago in America, but considered it impossible to solve at the time. 

We have made a new version maintaining the difficulty of the original and licensed it for the Cast Puzzle series. 

This is without a doubt among the most difficult of all puzzles. Don’t use too much force… the pieces should just slide apart.
