NWA 8154, Ungrouped Iron
This is an odd one, with 3-dimensional graphite sprays. The Meteoritical Bulletin writeup contains a plethora of information:
Paired irons include NWA 7795, NWA 8155, NWA 8539, and NWA 11530. Possibly others. At 5.2 kilograms after analysis, this would be the main mass of the group.
