Coming of Age MkII - Brian Young Mr Puzzle

Coming of Age MkII, designed by Brian Young (Mr Puzzle)

This 18-piece burr takes 19 moves to remove the first piece.    From the Mr Puzzle website: "In 1953 Willem L van der Poel, a leading Dutch computer scientist, set out to design a puzzle with as many interlocking pieces as possible and came up with an 18 piece burr that took 4 moves to get the second last piece in and 3 more for the last piece. In 1997 Mr Puzzle changed the burr to create a puzzle with 5 moves to get the last piece in. In 1999 he came up with this version which takes 19 moves to get the first piece out! 

This puzzle was designed by Brian (alias Mr Puzzle) without the use of a computer. It was however analysed using a computer program by Andreas Röver (see the end of this detail page) and he found an even more difficult assembly of the puzzle, being a level 14.10.3.2.5.11.10. That makes 65 moves for complete disassembly."  Puzzle is pristine and comes unassembled.
