The majority of these 19 episodes have not been previously released. The rare recordings have been digitally remastered to provide the best possible reproduction. An additional bonus feature is Radio Lives , a Radio 4 programme focussing on the career of Jon Pertwee, who played CPO Pertwee and a variety of other colourful characters in The Navy Lark . The box also contains an illustrated booklet with a detailed series history and cast biographies.
