Fidelity Radio Pty Ltd, Sydney. 

Miller {m} writes: (The label was) introduced circa August 1951 by Fidelity Radio Pty Ltd of Sydney. The company started in 1938 selling transcription records to radio stations. The label lasted from 1951 to 1956 with catalog raange 1001 to 1078. The bulk of the recordings featured Bobby Limb, his wife Dawn Lake or associate Johnny O'Connor. Miller [J] does not list the Fidelity label and thus presumably does not regard Bobby Limb and his Band as jazz (refer A040 below). The TV presenter is however recorded, on tenor sax, with Alan Nash and His Orchestra.
