Adam,
just to make sure that I'm not (and no one else is) misunderstanding what 
you may be saying here - nwa 1839 was originally classified as an L7 by the 
same lab that classified NWA 3133. Since that time nwa 1839 has been looked 
at again by the same lab and reclassified as a primitive achonderite - one 
that has essentially the same oxygen isotopse signiture and similar 
minerology as nwa 3133. I know people have drawn similarities between both 
stones and nwa 011, not because of a genetic relationship, but rather 
because of the fact that they both originate on previously unsampled parent 
bodies.


I belive David Weir published the preliminary reclassification data on the 
list not too long ago.
