Incredible! I used to work with British made telephone exchange equipment in the 1980's. It was built in the fifties, but used those same yellow metal covers over racks of relays.
That ka-chuck sound that plays about once a second sounds a lot like uniselectors clicking over. They were used to direct a machine like this to go through a series of instructions. Each ka-chunk indicates the selector has moved one step redirecting power to the next processing stage.
