Generally know as the 'Tels Equipment Room' this was the 1940s & 50s Control Room. Nearest racks house VHF radio receivers and radar  control equipment. Wiring looks messy as lot of patch leads to facilitate transfer of services to the new tower. The room at the end was home to the temporary Tower and Radar facilities in the 2000s
