Just finished watching the BBC4 doc about recording, in which a 4038 is introduced as a "Coles 4038 from the early thirties"...!
Firstly, the design dates from 1953.
Secondly, it was branded as STC until the 1970s.
Thirdly, and worst of all, it is the BBC's own design.
If the Corporation can't get its own history right, how are we to believe anything else in the programme?
