Hello Steve and List, I got my two slices today and I cannot help but agree! One of my pieces has a grey, glassy "megachondrule" measuring 9 millimeters in diameter! Yes, this meteorite is very porous, vesicular and highly crystalline - just like Baszkowka and Mount Tazerzait. When I put one of these slices under my microscope and looked at it at 16x, I also discovered a few beautiful, euhedral crystals in several vugs - another feature NWA 2380 shares with Mount Tazerzait and Baszkowka! My second slice features an orange-colored, much finer-grained angular clast measuring 7.5 x 7.5 mm. Not sure (yet) what that is. What I find hard to believe is that NWA 2380 should have a weathering degree of "only" W1. Metal - if any - is weathered, corroded, or maybe even altered, so to me this looks more like W3 (which doesn't diminish its beauty, of course!)
