In a radio sequel to "Dad's Army", "It Sticks Out Half a Mile", which is set in 1948 (three years after the Second World War ended), it is revealed that Mainwaring spent two years manufacturing cuckoo clocks in Switzerland. However, the first episode of "Dad's Army" shines light on Mainwaring's future: briefly set in the then present-day 1968, it features Mainwaring as guest of honour at the launch of Walmington's "I'm Backing Britain" campaign, where he is referred to by Wilson as a magistrate, alderman and chairman of the Rotary Clubs for both Walmington and Eastgate.
