With all the recent discussion about these Russian Blue insulators, I figured I'd post a few photos, of some I've bid on and (and won). The HEMAH 67 TC III are CD 569.2s, and I'm not positive about the CD of the others. I've seen the one on the left called "cadet blue" though I don't suppose that is an "official" recognized color descriptor. In hand, it is more of a "steel blue", distinctively different from the other Neman shades of blue.
