WOW Got a reply today (could this be the elusive case holder?)
Thank you for your e mail regarding your application for a registration certificate. Unfortunately investigations are taking longer than anticipated. I have had to seek further advice from another department, once the advice is received I will contact you again. Thank you.
Another polite email has been sent, including a copy of the dating certificate.
Watch this space!
No reply from the recipient of the email
but I did keep the truly lovely lady in the loop, got an automated reply that she was out of the office until the 6th, and today she replied " I can see that Norman factory closed in 1963 and can see your reply on the case. The clerk has passed it to the support team for further advice, sorry for the delay."
