Once again, I've gotta take issue with calling a stone that is only 10%
of the total recovered mass the "main mass". I don't think this is a
reasonable usage. Allende, Murchison, Holbrook, and now this meteorite
simply don't have a single main mass. Give Ward credit for the largest
known piece.

I also want to point out that classifications published in the Bulletin
are not official classifications. They are considered by the committee
to be authoritative classifications, which means they were judged to be
done by people with the proper expertise and their findings were judged
to be reasonable. But every classification in the Bulletin is nothing
more than a finding made by the listed classifier(s), i.e. the work of
one specific person or group.
