Sorry to barge in so late on a thread, but I wanted to thank
@raisinwing for the wonderful photos, which I've just come across.
I attended King Edward VI Grammar School in Stafford from 1970 to 1974. Every time I revisit Stafford I take photos of the exterior of this wonderful building, but this is the first time I've seen inside since then!
BTW, it seems the place is now being converted to flats, but the developer is being made to preserve as much of the exterior facade as possible. Presumably it's a listed building.
