Sorry people!

I was going by the description in the Catalogue of Meteorites. Obviously a
little out-dated but still with the most information as to the number of
pieces found, when and where.
And there it is listed as "Iron, Ungrouped" but with a nickel content of
4.9% so an Hexahedrite.

Anyway, it is not a meteorite you see very often, and it is so shiny I had a
very hard time getting a good picture. Thank you Michael for publishing it.

Enjoy it, I got more coming!

Hi all
What a very excellent image of an unusual meteorite. Thanks Anne for
sending it to Michael to be put up on his fine site.
The text below the image mentions structurally and chemically
anomalous. The chemical classification has been unofficially changed
to IIG. I say unofficial because no paper has been presented to define
the group...at least that I am aware of. Other members of the group
are Auburn, Bellsbank, Tombigbee River and Twannberg. The good news is
Grossmans DB lists it using the IIG classification....so it can
probably be considered official.
Also its structural classification is just a regular old Hexahedrite
with no need for the anomalous descriptor.
So it should be listed as an IIG, HEX
