Looking at the clips in this trailer, it would seem that the 'King and Castle' episode featured is the final one in the first series, 'Rivals' (08/10/1986) in which a collection agency employs strong-arm tactics. Interestingly, both 'Slinger's Day' and 'King and Castle' had two series, and each episode in their first series was shown on the same dates, between 03/09 and 08/10/86. This trailer would therefore have aired on 6th or 7th October 1986.
