History: Approximate year of manufacture 1959. This was originally designed as a microphone for recording. The ribbon was very sensitive and easily damaged by loud singing or blowing into the microphone. However, close-up vocal use was made possible by inserting felt "acoustic correction pads" into the head. The felt pad gave a degree of bass reduction and protection for the ribbon. An additional yellow fabric insert at the rear of the head altered the pick up characteristic from Figure of 8 to single side making it less susceptible to feedback and more suitable for PA use.

Other variations of the RB included:
RB/T with a die cast tubular mounting containing the line transformer and connecting socket.
RB/TS as above but longer to accommodate a sliding on/off switch.
RB/W with an oval die cast mounting containing the transformer and connection socket with separate " tapped hole for stand mounting.
RB/WS as above but with a rotary on/off switch in the stand mounting position.
RBS alternative impedance choice 30-50 and 1000 Ohms.
RBY alternative impedance choice 30-50 and 10000 Ohms.
