Vintage Hungarian Rings (difficulty 10 of 10)

Warning! There is mostly Hungarian text on the instructions.
These puzzles were found in a store in Eastern Europe. This is a vintage puzzle made in 1982. A game like this was patented by William Churchill in 1893. There are very limited quantities of this item.
The objective of the puzzle seems easy. Just return the plastic balls back to their original position but once you mix it up you'll find it's not as easy as it looks. Their are 38 balls in total with 10 red, 9 blue, 10 black and 9 yellow. Their are 10 trillion different variations and 8 different solutions to get out of those variations. Good luck.
