An insulator collector in Italy sent me these photos of a Fidenza 6205, 2 part insulator, (about the same size of a Pyrex CD 320), that he has. This is unusual in that the top part is a light purple and the bottom section is light aqua. Most of these 6205s are "ice" or clear color. II'llpost a photo of this one before it was removed from its metal pin, and cleaned. It's really this way. This one is probably a CD 381, I'll check in my GIFONA and see what CD is assigned to a 6205. This is very similar in size and profile to a Fidenza 2205 (dark green) and CA2205A (light aqua), but the top section is of a little heavier construction. I'll also post a picture of a 2205 for comparison.
