At "BI" there's only one person working, and they are wearing far too many hats. Alot of the old records are still in boxes, packed away and no one knows what or where things are. Then, again, the records may have been sent to the BOE. Who I doubt will know what they have or care.
What are you looking for, I may attempt, this summer, some research there. And I could check around for your info.
