There was an advert where a well-known actor - blond, blue-eyed, square-jawed type flew over a Barratt development. Early 70's? Probably refers to that. Wish I could remember his name.
he was in a few soaps
plane makers and 'compact' spring to mind
looks like or looked like the fair haired builder in Emmerdale. you know like Eric Chitteris looks like one of the kids in Please Sir ! with sidney poitier ( because er he was )
