Hi Guest
One of several reviews in CoffeeGeek mentioned 3 items of spares, supplied by Bodum, but the burrs wasn't one of them. I guess you've contacted an agent for Bodum and they may have confirmed this.
I suggest you phone Happy Donkey

You might get a good 2nd hand Antigua on eBay, or you may discover them to be the Bodum donkey graveyard for dead grinders.
Sorry I can't be of more help.
