Hi Ron and all,
Thanks for the story.
Two lines make me wonder exactly what meteorites they used in the research:

I ran a query for carbonaceous meteorites using the COM database and
came up with 36 witnessed falls, and 561 total. Winonites, a total of
11 listed. Brachinites, 7 entries.
Any more info or guesses?
Cheers,
Martin
