Going back in time - Divisions in August 1927

            Scanned from "Radio: Wings, Wheels, Wireless" August 1927

Extract from the above magazine:

"For the purpose of satisfactory control South Africa has been split up into eight divisions. Each division is controlled by a Divisional Committee. Each Divisional Committee has one of its members on the Executive Committee. With headquarters in Johannesburg it is obviously impossible for all Executive Members to meet regularly, so a proxy Executive Committee meets from time to time with power to put forward the wishes of the various Divisions."
