Hello Rob and List,

It's fairly consistent with what the Catalogue says. One specimen of
40 g was preserved in the Simpson collection. During a search in 1960,
not in but around the crater, 207 fragments were recovered, total
weight 1.1 kg. The largest weighed 57g and about half of the 1.1 kg
were oxidised irons and half mesosiderite. Within the crater 280
fragments, totalling about 20 lb were collected, all of which proved
to be highly oxidised mesosiderites.

So your specimen may be the one wrighing 40
grams or the other one weighing 57 grams.

Congratulations! Beautiful, rare specimen!
