Lap Compass

Sussex Inshore Fisheries Conservation Authority staff reported these artefacts.  It is unknown where they were originally found but they are on display in the mess room of Chichester Harbour Conservancy.

IFCA_30012 Warning panel IFCA_30012 Lap compass

The finds are thought to have come from an aircraft and potentially date to the Second World War. The find shown on the left above is a warning panel bearing the message: ‘WARNING DO NOT SWITCH OFF THE BATTERYCIRCUIT WHEN THE ENGINE IS RUNNING’. The find on the right is the dial and case of a lap compass and bears the inscription ‘Navigation Computer Mark IIIC’. It was made by Henry Hugh & Son, a London based firm who developed the first compasses for use in aeroplanes during WWI. It is likely that both of these finds came from an aircraft. During the Second World War many thousands of aircraft flew over the south coast to attack or defend cities, industry and military targets in Britain.


This find was discovered by the Royal Exile whilst fishing with pots on 15th December 1982. It is retained in private possession with the present Shoreham FIPAD contact. This exceptional find aptly demonstrates the value of material that can be reported through the FIPAD. Finds like these, without the safety-net and framework that a protocol provides, may go unrecorded.

 SHOREHIM_30004 carronade

This is an 18th century carronade which was known by sailors as a “Smasher”, presumably a reference to its destructive capabilities at short-range. The carronade was designed for close quarter engagements. Mounted on the side of a vessel it had the potential to fire a range of ammunition including cannonballs, barshot, double-headed chain shot, grape shot and canister shot. The short length of the breech of the gun compromised the range, but for close combat it was a practical and effective weapon.

Mammoth Bone

This bone was found in May 2012 and reported through the Fishing Protocol by Dave Robinson on the Betty Peerley. The vessel was using static gear and the bone was found in the Wight sea area.

FISHERMAN_30001 Mammoth Bone

This bone was correctly identified by the finders as a mammoth bone. Lorrain Higbee, zooarchaeologist for Wessex Archaeology confirmed this identification. This bone is the proximal end of the femur or upper rear limb bone. Proximal refers to the end in closest proximity to the core of the body (antonym: distal) and this bone would originally have had a ball joint articulating to the pelvis of the animal. This example has been damaged during its time underwater and shows characteristic rounded edges caused by water action.
