This was advertised on a popular online auction site with blurry pictures obviously taken by some sort of root vegetable. The total cost with postage was about $7.50 (converting from sterling). It gave me the run-around for a while but appears to be a quite scarce variant with these mint controls, most lack them totally. I was able to find two others of this variant sold.
