I decided to go out today to see some insulators that had been on our local Craigslist for about a week. Got a nice surprise when one of the insulators that looked like it was a CD 102 from the photo (which had been taken from above), turned out to be an unembossed CD 120. Looking this up in the price guide, it says this is a "wormser type". If anyone has any background about why this piece might be associated with the Wormser glass company, I would love to know about it. I know the bullets are attributed to Wormser but didn't know any other styles were.
