Did you ever come across the 'Ackroyd (sp?) Board'?
Yes, we had one at Strubby. Collections of different coloured map pins, with the call signs of all the Manby JPs and Strubby Varsities and Canberras [later, Dominies] - and a few blanks for visitors on which one chinagraphed the call sign
What fun you had, poking them into the little holes in the airfield diagram, to make the connection and illuminate the appropriate lamp downstairs. How one yelped when you stabbed yourself with a pin for the umpteenth time! Damn, those pins were sharp!
Our repeater was in Approach downstairs. Nothing in the GCA truck, of course, but Talkdown would be given circuit traffic with the 3-mile clearance, IIRC. It was useful to an extent, as Strubby did a lot of simple QGH approaches. I'm trying to remember whether we also had one at Tengah - I shall search some old photos later.
Invented by W. S. "Stubby" Akeroyd [subsequently gp capt] to enhance Flight Safety and Injure ATCOs
