An unprovenanced relic of Sir John Franklin's last expedition 1845-48. This is possibly the magnetic corrector for a compass. The item is a rectangular iron bar with grooves cut across both sides near the end. It has a Royal Naval Museum, Greenwich number (9) or (6) painted on. The 1913 catalogue gives Franklin Room, case 5, number 9 as 'Parts of a ship's compass.' It may be part of the material taken from the ship found off Grant Point by the Inuit and later collected on the Adelaide Peninsular by Lieutenant Frederick Schwatka.
