Adam,
Don't forget the big one. NWA 5400. In this case even with the word of a real Scientist, people had to wait for Oxygen Isotope comparisons. Luckily, The science proved pairings but, a self pairing is never a good idea.

We always get a unique number and claim the weight of the entire batch when multiples are found.? We submit every piece for examination and claim all of the weight at once.? In the case of NWA 2999, a thin-section was taken from every pebble.
