How did I know that the glass was by Nazeing? 'Cos I bought my version from their own factory shop a few years ago!!! From memory it was £12.00........but from what you say they haven't kept one for their records
I'm really surprised.
By the way I think that Nazeing should be added to the header since they were the makers of the glass.
Good that you now have all the info Jeanne
Kind wishes, Nigel
