Blind Labyrinth 1C

Wander the maze with the metal pin inside the black outer piece of this aluminum puzzle and make it through the labyrinth to the inner ring-shaped passage and then back again.  Because the maze can't be seen, this problem is solved with the sense of touch.  This maze is classified in grades A, B and C of which the grade C is most difficult.
Only 2000 copies made of this puzzle (most of them were sold back in 1984). Blind labyrinth was developed by Lauri Kaira in 1983. 1C is the most difficult version of the blind labyrinths.  Definitely an item for the puzzle collector!
Material: Aluminum.
