Hi truthseeker - I was a congregation secretary in the UK. Not sure why you didn't wait until after 25th May to request under the new regs but anyway ...
If you were not a Regular Pioneer, MS or Elder, Bethelite then there would be no reason for you to be on file at HQ unless you had been disfellowshipped or you had disassociated. (Or if you had written to them or had been mentioned personally in someone else's correspondence)
Publisher record cards were/are only kept at the local KH. Letters of intro only between congregations and letters to be discarded by receiving body once read to them.
