I was at a flea market set up and had this guy tell me he had a couple hundred insulators in his garage and had to get rid of them to make room. I went from the flea market to his house. He had a lot more than he thought, so I couldn't fit all of them In my truck. These are the boxes I brought home, I will go back next week to get the rest. He also said his brother has just as much and wants to sell them. I will post pictures of some after cleaning.
