I agree Carol. Etched irons are one of my favorites. The coarse octahedrites have "fat" lines in their widmanstatten patterns. Medium or fine octahedrites (and some hexahedrites) have very thin lines in their patterns. Generally, I prefer the thinner lines, like those seen in etched Gibeon. Although from time to time I see an interesting etched Campo or Diablo that has some inclusions or other traits that add to the overall pattern. You never really know what you have until you cut it open and etch it. One slice from a given meteorite might show a perfect smooth face with widmanstatten lines, while another slice from the same meteorite might be polka-dotted with silicate or carbonate inclusions. Each one is unique.
