That's a surprise Steve and thank you very much for the kind offer. There's no rush to find the 'safe place' as I'm still at the research stage and will get in touch in due couse if the need arises.

Thanks as well to those who have contributed thus far. Further advice would be most welcome. In particular, I wonder if anyone has any theories about how the blotch came into being?

Would also be pleased to hear from someone who has attempted polarising film replacement on this or any similar LCD.
