There has been very little written about Nori history, and there have been no college/university theses that I am aware of. It is a subject crying out for research whilst there are some former employees still about. At one time there was a member of the Nori board called John T Ellis. he owned a builders' merchants at St Annes and I have been told that he got a commission off every brick that came to the Fylde - millions of them. I suspect that you could get a grant towards your research =-PM me. First check in the library
[email protected]. There may well be articles in The Builder and similar trade journals. There was a British Brick ( similar) Society at one time. Ask the present owners what records they have. Also check in Lancashire Archives.
I can probably put you in touch with one ex-employee
