It does not compare in size to the amazing Sikhote-Alin mass but its beauty and symmetry are remarkable. For those who own Dr. Norton's Cambridge Encyclopedia of Meteorites there are beautiful frontal and oblique photographs of this meteorite on page 53. This is one I would definitely love to see in person one day. Best wishes, Jim Baxter > Peter Sch. wrote: > >> I am studying shield shaped iron meteorites.
