Further to a previous poster, in 2017 a complete set of 16mm broadcast prints was discovered, misfiled in the archives of a longstanding UK ITV broadcaster (thought to be HTV). The films have subsequently been digitised and were released on dvd later that year.
The original credits used in the first episodes had to be replaced. In these, at one point, Rupert spends a couple of seconds walking up a stairs made of giant books and into an impressive building frontage also made of books. Unfortunately a bored animator had added titles onto the spines that included "Matrons In Leather" and "Spanking" amongst others.
