Hi Jeff,

"...make yourselves useful..." ?

Seems that a touch of contempt for the List has
slipped out from between your keys.

"Garbage can" ?

Again, maybe NWA 869 might not be your favorite
meteorite, but surely it deserves more respect than
that.

As far as your question, like Mike and Al (and no
doubt other normally useless members of this List will
or have told you) 869 is abundant to say the least. In
fact, at the recent Tucson show, there were many
fossil dealers who had many, many kg of what might be
869, and likely much of that material is back in
storage or on a slow boat back to NWA given their
prices.

The reason for mentioning this is that while this List
may have its faults, it also has its limits, and the
complete picture of NWA 869 will hardly be filled in
by a single post here. Further, I know of at least one
meteorite dealer who does not partake of the fine
commentary of this List, but does possess many, likely
hundreds of kg of 869 - in fact I think he stores it
in garbage cans...

Cheers,

Dr. Martin Horejsi
