I bid on (and won) an insulator in an online auction based on photos. I had to drive to the other side of PA (8+ hours round trip) to pick it up because the auctioneer didn't do shipping. It didn't look like much with all the soot on it, but I thought I could see green in the photos. Here is a picture of it back lit in my light box and under lit with a flashlight. You can see how much soot is still on it. Not sure when I can get it clean since it's too cold to use muriatic acid outside right now.
