Returned to the BBC Archives by David Buck after he found it for sale and purchased it.

'Z-Cars' ran from 1962 until 1978. The episodes from March 1974 (after the one listed above) to the finale apparently exist. I believe the first four episodes from the series exist, only because I recall seeing them offered on video (so, unless I misread something, it seems they exist). I don't have an episode guide for the programme, so I am not sure how many episodes exist in comparison to the missing ones.
