[meteorite-list] NWA 3133

[Adam Hupe]

Hi Stan,

No less than four laboratories were involved with the classification of NWA
3133.  No laboratory has reported a pairing between NWA 1839 with a reported
TKW of 122 grams and NWA 3133 with a TKW of 2,393 grams.  You said that NWA
1839 had a TKW of over 3 kilos and was paired to NWA 011 and posted this to
the List.  I would say get documentation proving these claims or submit
samples for classification.   When the NomCom authorized paperwork is in
hand share it with us all.  I grow weary of all these fantastic claims
without proper documentation.  When proper credentials are shown I will
recognize pairings.

All the best,

Adam
