Horseshoes Cast Brain Teaser Metal Puzzle

Great well known cast Horseshoes metal puzzle.
The objective here is to separated the hanging Ring from the horseshoes. The Horseshoe puzzle was included in the boxes of Uncle Sam's Puzzles from 1920 but as early as 1915 boxes of puzzles were being sold in Germany which included this puzzle then called the Ring of the Nibelungs which was shaped from wire.
An oldie but a goodie. Still just as much fun as it was way back then.
