I was there from 1970 - 1975, Mrs Ford was the Headteacher and another teacher, (geography), Eric Milner was having a relationship with a girl in the year above us when we were about 13/14, we knew because her younger sister was in our year and it wasn't a great secret.
I'm pretty sure the link below is him, the dates and info seem in line but they called him "ten Bob Turner" in court. I can assure you he was "Bummer Turner" to all the kids at the time. I remember one kid who came from a very deprived background who wore his Dad's "hand me downs" including shoes that were far too big for him, he was of his main victims from our year, the poor lad spent evenings and all weekends at Turners house, I guess being sexually abused and getting fed was the lesser of two evils away from his chaotic/physically abusive home life.
