[G6Tanuki]

Crabtree stuff was always reasonable-quality - along with MK, Wylex, GEC and BICC. There were other brands of distinctly-lower quality [Marbo, for example, or W&G].

At my secondary-school most ordinary classrooms only had a single 5-Amp BS546 round-pin power outlet - a bulky black cast-iron lump with a switch, surface-mounted and fed via conduit. The art-room and geography-room had extra sockets [to feed floodlamps and a wall-hung, rear-illuminated mapholder]; I remember when the languages-room was refurbished they added a 13A outlet and fused-spur-box alongside and fed from the existing 5A socket so a tape-recorder and slide-projector could be used at the same time. Those of us not of a linguistic persuasion took to stealing the 5A fuse from the spur-box which - for a while - meant we could escape the tiresomeness of French tuition.
