Collection of 9 Vintage BBC Engineering Training Manuals (ca. 1970s/1980s)

A slice of broadcasting history! This is a collection of 9 official "Programmed Text" training manuals from the famous BBC Engineering Training Department (Woodnorton).
These were used to train BBC broadcast and sound engineers during the 1970s and 80s and were given to me by a BBC engineer when the training facility updated its material in the early 2000s.
These are fantastic resources for vintage electronics hobbyists, audio engineers, ham radio operators, or anyone interested in the history of the BBC.
