A while back there was a thread about twin insulators. I have finally got around to getting a picture of my contribution. I bought these two CD 102 BAR/<> at an antique flea market for a couple of bucks. When I got them home I discovered that they are both from the exact same mold. The irregularities in the shape of the diamond and the placement of the bar are identical, as well as the colour. What is unusual is the one on the right has only 3/16" of dome glass while the left one has 9/16" of dome glass. The left one also has an off-center pinhole with a thick blob on one side and extra thin skirt on the other.
