I have vague recollections of an article in either our journal or that of the Norfolk FHS and do not wish to duplicate.
I've found some info in the British Newspaper Archives if you're interested?

I think Val did an article in our journal recently.
Thank you both.
I have found Val's article. It was in March. we have been in contact about it.
Thank you for the link.
