Hello List,
I think the buyers of the 'Moss'-meteorite should be aware of the
fact that there are two kinds of material coming from the fall in
Moss, Norway:

1) The freshest is the material that was not affected by the heavy rains
from about the 30th of July.
Before this it was all dry (and the farmers complained it was the
driest summer in many decades). I was there myself in Moss only in
the dry period.
As you may know, only me and Mazur and another finder collected our material
on the 19th, 23rd (and 24th). Se my erlier posting:
http://six.pairlist.net/pipermail/meteorite-list/2006-August/186289.html
(E.Twelker will also have this same material in some time - see his posts.)
This is well before the rains started.
This is also the only material from the biggest piece found.

2) The rest of the material that is available has been collected well after
  the rains started.

One world class american meteorite classifier has seen both materials and
has commented that the 'after the rains material' is clearly more oxidized.
So to get the only existing original pristine material the only source is
Mazur,
myself (and later Twelker).

Be aware also that this material can be a new group of carbonaceous
meteorite as it contains small white CAIs, isolated olivine grains, but do
not look
quite like other COs. This might make 'Moss' the type specimen of
a new group with one member? So, maybe the price is not very high
for this material...

Contact me off the list for price/weight and order information.
(Tomorrow I will also have a page for this at:

Best wishes,
Bj?rn S?rheim
