Just watched a very interesting programme on BBC4: Hidden Histories, Britain's Oldest Family Businesses. Episode 2 is about Toye & Co (now Toye, Kenning & Spencer) who've made regalia for many generations including for the Military, the Suffragette movement, the Freemasons and for the 1953 Coronation at Westminster Abbey. They operate in 3 locations: Birmingham, Bedworth and London. A nice family business history which has evolved to survive many economic ups and downs. Not sure if the link below will work, but if not the programme is available on iPlayer. Currently 29 days left to watch this episode. Viv.
