We got these insulators from a country junkyard run by a woman who must have been in her 70's. She saw my ad in the paper and called me because she said she had some insulators that were smaller than the normal ones. When I got them home and cleaned them off I found that they are really fizzy. All have some damage to the drip points and the one has a good crack in it. I pictured them with one of my Hemingray Blue Hemi-42s. They look pretty blue to me, but certainly not as dark as the Hemi-42. One has a stripe of amber in it and a quarter inch bubble, another has a quarter inch bubble, another has some light snot in the dome along with the fizz.
