Yes, I experienced very similar methods in the late 1960s & early 1970s, plus detentions which were for 1 or 2 hours, or sometimes on Saturday mornings and or having to write out large amounts of "lines". The prefects could also inflict lines and detentions as well as the schoolmasters. I was amused recently when a godson complained that he was given a detention, he had to stay behind for just 10 minutes. Hardly seems worth it really. Having to do lines in your best handwriting was so tedious, especially when my handwriting was and still is rather untidy. Sometimes, if the master thought it was too scruffy, I had to do a larger number the next day.
We also has the teachers as mentioned above that threw the chalk and board rubbers, the Geography master was an expert shot. In some ways the lessons taken taken by the strict teachers were better than those taken by the softer ones as you could get on with you work with less interruptions etc.
Mind you
having to wait outside the headmasters office prior to getting any punishment was often worse than the punishment itself.
