Thank you, I'll post the pictures again in "The Road Bike How Much Thread".
Yes, Fred Williams is a bike shop in Wolverhampton that is still there today. My brother tells me that only the tires and the saddle have been replaced, everything else is original. He bought it to ride to and from school and hasn't ridden it since getting a car - he's 50 this year.
Neither of us are into retro bikes so I said I would look into how much it might be worth so that he can sell it to make a bit more room in his garage.
