Leica, small world! The radar development work was commemorated on the science block roof by a small radar head. I always assumed the block was 1960s, but I guess it actually may have been built by the Admiralty during the war. Looking at Google Maps, rhe Oceanographic Institute buildings have been demolished and are now some horrible looking housing development, maybe for the teachers? I recall Prince Philip visited the Oceanographic people around 1978 and arrived on one of our playing fields in a Wessex.
Somebody here (Treadders ?) must have it to hand
I haven't got it I'm afraid.
