I remember that, in the MPN11 GCAs in the '60s, we had UV hand lights

Oooh yes! I remember it well ... the lights glowed without being plugged in as there were so many electron thingies flying around inside the cabin!!
When the AR1 radar was being installed at Finningley we were lent one of the trucks from Sleap to tide us over. The first thing that happened was Chiefy from GRSF demanding our screwdrivers so that we didn't upset his delicate settings with our 'tweaks'!!
P.S. Do you remember the trick Cat Board question "When is a GCA truck IMC"?
