Ralph, I think I mentioned it on Greenkeys when BT Heritage first put it 
up, but it's certainly worth reminding folk.

The works are based on the Creed models, like the No 7.

BTW there are a number of other heritage films from British Telecom on 
the 'Let's Talk' YouTube channel. (Along with a lot of modern publicity 
stuff).

And even more, but mostly telephone related on their history site. Have 
a look at 'Getting the most from Telex', 1977, on here:

The actor in the film is Peter Jones who was the voice of The Book in 
Douglas Adam's radio series of 'The Hitchhiker's Guide to the Galaxy'

Cheers,
Sam
