Infants school long gone, houses there now.
Junior school, still standing with modern additions and the railings dividing the boys and girls playground have been removed. Hopefully the toilets are inside the building now. The milk was indeed kept nice and cosy next to the radiator, I never drank mine I always swapped with the boy who sat behind me, my full bottle for his empty one. I had a look on the school website and there are only 100 more children in the whole school now than were in the fourth year when I was there, 'baby boomers'!
Grammar school was situated in a beautiful 19th century country house, it had a 'carbuncle' added in the sixties which I don't think planning would be happy with today. It is now a thriving comp. with boys and girls not just genteel young ladies.
