It must have been re-introduced as I remember it well into my teens either in rolls or boxes. Izal and Boots own brand were what we had at home but rellies had Bronco.
Similar product was in the bogs at school each sheet endorsed Now Wash Your Hands. WRCC. WRCC was of course the West Riding County Council but we came up with a number of (rude) alternatives in which the the C stood in for female gentilia.
Hard paper was still standard issue on government departments until c1982 when they supplied the soft stuff. We were given strict instructions to use the older stock first...
I remember it at primary school.
Not sure about a 'big school' I seemed to have blotted (hur hur) most memories of that out..
