A question and a comment:
What are those pictures (prints?) on the wall of the ‘top class’?
And the comment: when I worked in the successor school in the 1960s -- Walworth County Secondary School, comprehensive -- you could see the boys as the central school scholars’ direct descendants: still smart, well dressed, happy and alert, except for that poor or neglected minority that would never have got into the central school and for the most part were in the ‘remedial’ classes, though these classes, too, had thoroughly wholesome-looking children. The introduction of mixed-ability classes in the second half of the ‘60s was a welcome and successful reform.
