Join me on a factory tour around the Her Majesty The Queen's button maker.
Established in 1655, Firmin & Sons are the oldest, privately-owned manufacturing company in the UK.
At their prestigious metalworks in Birmingham they make not only buttons, but also ceremonial armour, helmets and other accoutrements.
Firmin & Sons' sales manager, Tony Kelly, takes us on a tour to discover the rich heritage of a manufacturing firm that has held a Royal Warrant since the reign of George II.
