This is a sleeper that I had packed away probably 3 or 4 years ago. Pulling it out of the box last month, I was amazed to see that the glass below the wire groove is completely opaque and is almost a milky-jade color.

It is difficult to photograph well, but the area below the wire-groove on this insulator is 100% full of milk and it even has little milky "fingers" that reach up into the dome. There are a few amber stringers to boot!!

Thanks for looking!
