Does anyone know where or how I could locate one of these lenses. I am not talking about the original cool blue but rather the gold plated poly carbonate made by 3m that was discontinued a few years ago. Had one and loved the clarity. Welds with a greenish color.Recently had my hood with this particular lens in it stolen on a job site and have spend weeks trying to find a replacement. If anyone has one they would be willing to part with I would appreciate it if you would send me an email. Or perhaps I could luck out and find a batch sitting on a shelf in an overstocked warehouse. Thanks
