When I was there (late 60s/early 70s) we had a school cottage in Wales. The school 'minibus' was an old ambulance painted red, black and white (school colours) with a load of old Midland Red bus seats bolted down in the back. No seat belts, no windows. If you had a good form teacher he would take us out in the Bus after school on Friday and we would spend the weekend at the cottage. It was pretty basic but fun. Our form tutor was Mr Glauert who also taught us French with differing amounts of success!
