Some episodes of this series are missing, believed lost.
The vast majority of episodes were produced in Sydney, and produced by station TCN-9. However, there were also a number of episodes produced elsewhere, including in Melbourne, Adelaide, Brisbane and Perth.
When the series began in 1958, it aired live and generally not recorded. Starting in early 1960 the live transmissions began being recorded as kinescope film prints. The 23 April 1960 episode appears to be the earliest for which a kinescope recording has survived.
