Would you have a picture, Mike?
When I was 14, I did work experience with BT and actually saw the backup batteries in use at that time.
As I recall, they were made from Plastic when I saw them, but you may have an earlier version of the same sort of backup device.
Ah, the days of Strowger gear, System X and (second hand) System Y.
