The Met Bulletin description contains the sentence "A significant
portion (1/3) of the stones consist of a dark, fine-grained impact
melt containing mineral and chondrule fragments."

Funny when I google it, hundreds of papers discuss the metric ton of known Chelyabinsk as all being impact-melt material. Of course, those of us who went there and have a large amount of Chelyabinsk can tell you that it sure seem full of clasts, and melt pockets and shock veins. Since his kickstarter rock seems to be the only known LL5 melt (according to the (met. Bull.)and Chelyabinsk seems to be nothing of the sort, it is amazing to me.
