NBN News here in NSW, Australia just aired a piece on Ainsworth, once it going on-line I'll link it here.
But in summary, George approached Ainsworth, he sculpted a prototype, George said yes, and he produced 50 of them. Then he couldn't sell any at some market in '85, and after winning the lawsuit, he now sells them all over the world, with apparently his biggest market being Australia.
Dunno, but not a single mention of anybody else except himself. And this was coming from the reporter specifically. Might have a chat to NBN about their research, because it was mighty poor. (But please excuse me, journalism seems might poor these days - atleast how much research is concerned.)
