Hello John and list,
I recently picked up a small piece of NWA 2677 from John Birdsell. An interesting iron meteorite of 100g. It has been provisionally classified as a ?IICD (aka: IAB subclass LM).? noted from John? website. I am not really an iron expert, but I guess that means fine octahedrite. The meteorite itself is somewhat confusing, as the nickel content doesn? seen to line up well with any of the IIICD? except the Ataxites I suppose, but this has a obvious bold octahedrite pattern.
I managed a pretty good photo of my slice on my collection page. (I now have studio lights and equipment...which also of course means, my camera is giving me problems now...:-(

Also, John asked about possible pairs. Doing a little research on the iron I have found the following meteorite classified somewhat close and location of find possibly close. Could this be a possible pair?
Hassi-Jekna, IIICD, found El Golea, Algeria in 1890, TKW 1890, Bandwidth .47mm.
