[meteorite-list] Speaking of IMBs

[Darren Garrison]

I'm not trying to sell this, so I'm not undercutting anyone's prices, but I've been wondering about
this half-stone of mine for a while.  I got it from Dean Bessey on Ebay earlier this year, it has a
highly weathered exterior and is (without measuring) around 4 inches across and around 180 grams.
It looks like an impact melt breccia to me, and I was wondering if anyone else agreed/disagreed on
that (I know that it could use better polishing):
