Edward VIII Postbox Converted to George VI

"Although the monogram on the enamel plate shows this as a George VI box, the initials on the aperture casting have been modified. This was originally an Edward VIII box, that was adapted during the manufacturing process. As such, it's probably unique." Quoted from 'On the Trail of Edward VIII' by David Chandler.

In the UK, a Ludlow wall box is a post box where mail is deposited to be collected by the Royal Mail and forwarded to the addressee. They are built into stone pillars or the walls of buildings and are never found free-standing. This is because they are made largely from wood. They were nearly all made by the now-defunct company of James Ludlow & Son of Birmingham, whose name they take. Similar designs exist as historical artefacts in certain Commonwealth countries. Ludlow style boxes have been in use since 1885 and were in continuous manufacture until 1965. Quoted from Wikipedia.
