I've had a further look and the actual maker of Branston Beans is Princes (who are owned by Mitsubishi Corporation). They use the Branston brand name under license.
Crosse & Blackwell are also part of Princes, but it appears Princes use that brand just for soups these days. So I doubt you'll find Crosse & Blackwell beans, but Branston are better anyway.
Creme Eggs previously used Dairy Milk, they changed the chocolate and it's much worse. The maker of Wagon Wheels always says that they haven't got smaller, and it's just that they appeared bigger because of us being kids.
