Well, I haven't looked at an insulator for several years. Used to know the provenance of each and every one by heart. Totally lost now and no paper backup records. I count almost 300 in this display. A few are damaged (long story), a few duplicates to make a better looking string. I would say well over 200 are different, either colour, manufacturer or hardware. I believe all are either Ball/socket or clevis . Stand can easily be disassembled and is included if you want it. I am not going to load Bills site with pictures that have limited interest. Ask me for more. IF you are serious, I will spend a warmer day and get a list together. $3,000 . Located Toronto Ontario area
