 The Crusade, along with many others, was originally destroyed by the  BBC. In 1978, when the Film and TV Library in the UK was audited,  The Wheel of Fortune (Episode 3) was recovered, but, unfortunately,  the other three episodes were not. However, in 1999, The Lion  (Episode 1) was returned to the BBC archives by a private film  collector who had purchased the episode in New Zealand.
