This has got to be the record for the smallest engraved star on any Star embossed insulator. If you look hard at the center insulator, you can see it. There is an average sized star embossed on the opposite side. I measured the small one at it's widest points with micrometers at 0.140" - slightly larger than 1/8".

Makes you wonder if the engravers were having a contest. Let me know if you have one of these - I have not seen another. Also, note how low on the skirt the star is embossed compared to the others.
