F = Fluted box

The first Fluted boxes, a pillar box design loosely based on a Doric column and cast by Smith & Hawkes of the Eagle Foundry, Birmingham, appeared in 1856 and had a vertical aperture. In 1857 the design was changed to provide a horizontal aperture. Fifteen Fluted boxes, including both types, are known to have survived in the UK.
