There’s a local educational authority stamp on one page, but hard to distinguish a region of the UK, possibly we are looking at a school in the north, where the strap was more favoured. The stamp could have been placed in recognition of the inspection process, if so did the inspectorate turn a blind eye to the reference to rubber tubing, rather than the official cane or strap?
It’s Barrow-In-Furness on that stamp.
In that era, that town was part of the County Palatine bit of Lancashire that was cut off from the rest of Lancashire by a bit of Westmoreland.
Lancashire was definitely one for the strap in most cases, as opposed to the cane, and that applied to girls as well, from the memory of a couple of girlfriends who were schooled in Manchester & Preston respectively in the 1960’s/70’s. Unfortunately, said strap put them off the idea of being spanked by me
