I have a repro TZ PF that I bought and put it In the closest for a year. When I took it out every inset was milky white. I sent it to someone to see if they could fix it and it could not be fixed. I tried sanding it down very slowly as an experiment but you know wheat happened, I just sanded into the ink and that was the it. I never threw it away but the o my thing I could think of it being good for is for someone to make a white wood or a returner out of it. Ideas form you creative people?
