However, some Postboxes are always permitted to keep the designation of older (Constitutional) Monarchs. Within the grounds of Windsor Castle, for instance, we have observed a Postbox dedicated to King Edward VII (reigned 1901-1910) – with another Postbox in Oxford dedicated to King Edward VIII (who only ruled for the single year ‘1936’ – before being replaced after his ‘Abdication’ by King George III). Perhaps the above Postbox was constructed as early as 1910 – meaning it is currently 113-years old! Without knowing it, when this Postbox turned ‘100’ in 2010 – my family lived right next door to it!
