Church bears a portrait of Florence Nightingale who is interred at the churchyard. Fingers can be square-ended (such as in Cornwall and Norfolk), curved (as in Dorset) or triangular-ended (as is common in Somerset). Where timber was used for the fingers, place names are composed of individually affixed metal letters. Mileage is typically measured to the nearest quarter mile, with fractions being mounted on a separate ready-made plate, although measurements to the fifth or eighth of a mile are given in East Lothian. Due to their age, some fingerposts have 'fossilised' the historic spelling of places which was dominant at the time of their construction. Examples include "Portisham", rather than the modern spelling "Portesham" and the pre-decimal "6D Handley" for Sixpenny Handley in Dorset. Some fingerpost arm examples include the A- or B-road number as well as the destination, although many more of these examples were removed and replaced after the 1964 regulations were introduced. It appears that the original convention was for A-road numbers to be in white on a black background and the converse arrangement for B-road numbers, although there are few fingerposts with this as their current scheme. Although most fingerposts are a combination of black, white or grey, other colour variants exist. The most well-known are the small number of Red Posts which are found in some of the southern English counties, including four in Dorset, including one on the A31 trunk road at Anderson, between Bere Regis and Wimborne Minster. The others are located at Benville Bridge, Hewood Corner and near Poyntington. Various theories have been put forward as to their colour, including being to mark routes used by prisoners on their way to port for transportation to Australia, or the site of a gibbet. Other places have fingerpost arms with white writing on a green background which indicates the most minor of lanes, sometimes known as 'drift roads'. Post-Worboys fingerpost designs Some highway authorities chose to apply the spirit of the Worboys regulations in a fingerpost style, including the use of the Transport Heavy typeface. Arm materials have tended either to be aluminium or plastic. Devon County Council introduced triangular-ended fingerposts with edges in four different colours to illustrate the suitability of the route for various types of vehicles, from black (for most vehicles, on A- and B-roads), through blue and brown to fully white fingers, indicating local access only.
