Tuhia he haere tonu mo tenei whitianga - Ko tetahi o nga waka Whakawhitiwhiti Whakawhitiwhiti o te BBC, MCR 1 (he poto mo te Mobile Control Room), i hangaia e te kamupene Marconi-EMI honohono a i tukuna ki te BBC i te wa tika ki te pouaka whakaata i te Coronation o George VI me Elizabeth
i te marama o Mei 1937. He ōrite te MCR 2 ki te MCR 1 ā, i tukuna i te raumati o te tau 1938. Ka taea e ngā MCR te whakahaere i ngā kāmera e toru. I te timatanga, he paerewa Emitrons ratou, engari i muri mai ka whakakiihia e Super Emitrons, he pai ake te mahi i nga paerewa i te marama iti. I hangaia nga MCR ki runga i te papa o te pahi AEC Regal kotahi-papa.
