According to BB this variation goes to the alum toy set shown p137 BB. Neat set if ya ain't checked it out you ought to have a look. I think most of these toys, even being aluminum would bring more than what the book suggest. Most I have never seen, not even on that eBay thing. If a child did use these as toys ,I can see to where the would be broke very easily. Step on it break handle right off, or crush the pots.
Oh and Will, please start keeping notes of items sold on eBay, I can't catch them all! ;) ;D
