I have many more pieces if anyone is interested. :-) As far as I know the TKW is still at best uncertain. I have copies of 2 reports on the composition of Tafassasset. One from the Musee d'Histoire Naturelle in Paris, and the other from the Max Planck Institute. Both classify Tafassasset as a Carbonaceous Chondrite, Renazzo-type, with relict chondrules. I also have some thin-sections of Tafassasset, if you would like to study it and decide for yourself. :-) Let me know!
