I have a few of the Sediver N12P/146DC fog type glass insulators for sale. These are rated at 25,000 pounds M&E, the glass is a neat ice aqua color and measures about 10-inches across the widest part of the shell. They weigh about 10-pounds. These are a special design made by Sediver for New Finland Hydro power in Canada. I am asking $20.00 each plus shipping. Or if your in the San Antonio Texas area let me know and you can come by and pick up a few. Happy Collecting. Tom
