If anybody has pieces of, or has seen, both Hamada du Draa 
(a.k.a. Mhamid) and El Hammami, I'd like your input on this:  
could they be the same meteorite?  These share many characteristics 
in the reports I have on them:

1) Both are vaguely "witnessed" falls in NE Africa (Algeria, 1995, and
Mauritania, 1997, respectively).  Both were collected by locals
(nomads) a few days after they fell.

2) Both are H5 chondrites, shock stage S2.  Olivine comp is similar.
They were analyzed by UCLA and Munster (Rubin and Weber).

3) Both have fine metal veining.

4) Both are huge (over 200 kg).

What do you dealers and collectors think?
