Very faintly embossed, CD 320.5, MIVA, UNES 1205 (1 part, 2 skirts / shells, 5KV rating) insulator in a light citrine / yellow green. Nearly same dimensions as a Pyrex CD 320. This one has lots of "straw marks" on the outside.

The embossing MIVA // 1205 is very weak, on the top, either side of the top cable groove.

I now have a MIVA UNES 1205 CA, in blue aqua color, which is coming to me. First one of this color that I have seen. To see this one, [id=183370506]
