Picked up these two years apart, and noted a similar profile. The right one is crudely gorgeous, possibly my favorite out of hundreds on my shelf. It was allegedly picked up around the Santa Fe depot in Santa Fe Kansas. It has Pennycuick features throughout, and millions of the tiniest microbubbles I have ever seen in an insulator. It has a very low inner skirt groove, like most CD 147's have. They kinda look like Grand Canyons, until you set them next to one. Profile is most like a CREB, and the bases are rounded, not flat. I would like to know how many of these are around. Email me and let me know!!! Thanks!
