An early view looking north through Rooms 14 and 13 in May 1958, with work being overseen by Donald McWhinnie, who's making notes on his script. Daphne Oram is cueing up a disc on one of the turntables on a BBC TD/7 gramophone: note the parallel-tracking arms. To the right, Desmond Briscoe is editing a tape on a Ferrograph recorder, alongside 'Dickie' Bird, who's resetting a cue on a tape of prepared sounds. The equipment bays on the left remained in use until the late seventies. The turntables in the foreground don't appear to be a standard BBC variety.
