Bernd is right about Bath Furnace, it is a very interesting witnessed fall. So I thought I'd add a bit more to the story. The following link is to an image of a Bath Furnace part slice from Al Lang's website: http://www.nyrockman.com/museum/bath-furnace-58.htm As you can see it has a characteristic mottled appearance that was apparent when the meteorite was first broken. Ward stated: "The inner structure of the stone...is quite compact and dense, taking a good polish. It is a light gray base, blotched evenly throughout with patches of clove-brown iron oxide. Most of these are cloudlike in indefinite contour...That the brown blotches before referred to are due to the oxidation of iron can not be doubted; but as there has been no opportunity for this process to have gone on, either since the fall of the stone or during its passage through our atmosphere, the question is raised as to [where] its having found the oxygen in the parent body from whence it came?" The TKW of Bath Furnace is 86.5 kg and the main mass is the oriented 80 kg stone that Bernd mentioned and linked. It is a show piece at the Field Museum of Natural History in Chicago. That leaves only 6.5 kg for other institutional and private collections.
