Hi Tom, Pete and List,



Tom has been doing a fantastic job with his studies and I thank him for his
tireless efforts and for sharing with us. Before the realization that NWA
2828, Al Haggounia and the other pairings to NWA 2828 were found to be an
EL3 and NOT an aubrite, I spent many trips to Morocco buying up the "Blue"
material. Needless to say, I have several kilos of the "Blue" EL3 material,
one of the lucky first-in buyers, not price-wise but material-wise :-)



Here are some additional photo links of NWA 2828 "Blue", most have seen
these as they are the ones I have with my eBay description of NWA 2828.

Enjoy!
