As far as the BBC are concerned only 16 of the 52 editions are currently held in their Archives: 11 on the BBC's original colour masters as transmitted, and the final five episodes as monochrome film prints returned from New Zealand. BetaFilm and/or ZDF in Germany do hold 35mm colour telerecordings of all 39 episodes from the second season onwards; however these have only the dubbed German soundtracks. (Amongst these does remain an English-tracked edition not held by the BBC,
A Family Affair (1971)). To further muddy the issue, some prints feature alternative footage which UK viewers never saw, and vice versa. Such differences even extend to the credits (the German copies retain the
John Levene "running man" sequence even after it had been supplanted in the UK originals). A monochrome English-soundtracked 16mm copy of
Murder in Munich: Part 1 (1970) was eBayed to vintage TV organisation Kaleidoscope in July 2023. In November 2024 they announced they'd married this original soundtrack to the German telerecording, recreating a lost episode.
