Hello Kai,
You might be interested to know that your specimen is paired to NWA
2836, 2999, 3164, and 6291.

But I checked the Meteoritical Bulletin, and there are more pairings!

NWA 3158, 4569, 4662, 4931, and possibly 4877 are all part of the same
fall, apparently. And that's not me talking - that's NAU and the
Meteoritical Bulletin!

So your specimen is actually a piece of the second-largest angrite
ever found, and is part of the only known angrite multiple-fall; the
reported tkw of the fall is approximately 5 kilograms if you go by the
bulletin (6kg if you include 4877), but there's probably a bit more
out there.

Beyond that, well - we've gone over NWA 2999 and its relatives quite a
bit in the past few list messages on angrites. You can check out the
paper that suggests they're from Mercury. It describes a stone that's
paired to yours, so...kinda cool.
