Huzzle - Enigma

Patented in America in 1975; the somewhat swirled pieces of this puzzle by Eldon Vaughn must be disjoined and then put back together which was thought to be impossible to solve at the time. This new version maintains the difficulty of the original and without a doubt among the most difficult of all puzzles. Don’t use too much force… the pieces should just slide apart.
The key word is “twist”.
