I also got this one from another seller in Italy, he says it is from Romania, the color is a sage-green, and there are some very faint "ghost"markings, too faint to read, and a small "3" embossed omn the skirt, just above the base.. Similar to a CD 537, but it has a longer inner skirt and straighter sides. I'll post a better photo and add the measurements, after it arrives - which occured on December 4th. The dimensions are: 5 1/2 inches tall, X 3 3/8 diameter base, and the "head" is 2 1/4 inches diameter. The sage-green glass is exceptionally clean and clear, only a few very tiny bubbles, update: Thanks to Zoltan for the update information on this insulator, this is from Romania, and is listed as a CD 578.2, no name, unembossed, although not listed in GIFONA, it is on the current CD list maintained by Woody..
