Hello Everyone,

Re: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=6620167638

Today, I met the seller of the auction that has been in question, by me and
several others today. Was able to examine it, take photographs, but I was
not able to declare it a meteorite, or a meteor-wrong. Me and the seller
had came to an agreement that if I thought it was a meteor-wrong, he would
end it, and I do not at all believe he is trying to cheap anyone. However,
since I was unable to declare it a positive meteor-wrong, it is up to him
what he does with the specimen.

You will note yesterday, to the Meteorite Central, I labeled it in title,
"Mexican Meteor Wrong in Wichita". In my many communications I have given
it several names, including "Wichita Meteorite", but there is a Wichita
meteorite, this was not found here, and I am associated with the Wichita
meteorite, a very beautiful stone and so I didn't like that title either,
nor do I have a good title for it, outside of "specimen", which is what I
will use in the rest of this report. The owner was being elusive in my many
e-mails with him, which further gave me suspicion, since I had not seen it,
so after my 15-16 e-mails...I started more calling it Meteor Wrong. Here I
used the sellers title as I lack a good name for it.

Now I have seen the specimen and here are my thoughts.

It is my opinion that the specimen is not a meteorite still, however I would
like to have cut a piece and do a nickel and acid test before I really could
say much more then I am now, or send a piece off to UCLA for an opinion much
better then mine. Unknown irons can be funny as some of you know. The
seller needs money right now and although I have pointed out the advantages
of having it classified, if it is a meteorite I could help him make it worth
a lot more, if it is a meteor wrong, it would keep him from ripping someone
off, as he does not have it declared as a possible meteorite.

One big problem is it failed the streak test. It streaked gray VERY easily.
  This is enough to keep me from buying it without further study, which
looks like will have to happen from the buyer. Also according to the owner
the specimen has not been cleaned or treated in any way. And it does not
have the surface characteristics one would expect from a meteorite straight
from the field. There is also some red coloring I can't account for, it the
owners statement of having not cleaned or treated it is correct. I commented
on this to a few people I was in contact with and no one else seemed to see
the color in the auction. Magnetite and Hematite, the two most common
meteor wrong are usually found associated with other minerals and rocks.
And therefore many of the meteor wrongs I have seen that were magnetite or
hematite were associated with other minerals and one thing that seems common
to me is red coloring on parts of the surface. Perhaps that is why it was
easier for me to see in the auction then for others but you will see a good
example of this in one or two of the photographs I will provide as well.

However, the regmaglypts look much better in person then in the photographs.
  It does look oriented somewhat, at least from one view I will provide, and
there are sections of the stone that almost appear to be triolite
inclusions, which I will also show. My rare earth magnet really liked it,
giving a pull very comparable to the Canyon Diablo I brought along....one of
several example meteorites I carried. It also has the weight I would expect
from a meteorite. The most flat side I wanted a good photo of and it was
someone difficult for my brother and another person to hold it setting on
one side while I took several images to insure I got a good image. I have
also never had a magnetite or hematite stone appear as magnetic as Canyon
Diablo. If it is not a meteorite, it is the best meteor-wrong I have ever
seen. These are the reasons I will not declare it a meteor-wrong.

If a list member does read this, I would be very interested in learning
classification results, should they choose to classify it....which I think
they should. And I will answer any questions that anyone has directed to me
as best I can, however for the most part I feel my role in this specimen is
now over. I am not the owner, seller, bidder and I am not going to try to
have the auction ended, an option I was looking at when he was being very
elusive.

And now, the photographs I took. Which show its real color and are much
better then those provided by the seller.
