The widespread manufacture of low price goods in China had been at full steam for over a decade, closer to two, by 2005 the date of first manufacture of the ball. And the manufacturer couldn't find the original designers' details. And laid no claim to copyright (which seems strange). Perhaps it was the case of a knockoff of a knockoff of a knockoff. A CAD file from the 1990s bumping around commodity manufactures via QQ and USB sticks, the design adapted the next order of 10,000 items by any one of a multitude of small commodities producers. Having sourced during that time to now, I'd fully believe it.
