A gilt metal button with shank, bearing the crowned fouled anchor within a rope twist boarder from the 1845 British Northwest Passage Expedition led by Sir John Franklin. The Royal Naval uniform button, as worn by commissioned officers (military, 1843-) and civil branch (1835-) is tarnished.

The button was one of a number to be bartered from a group of Inuit near Cape Victoria, Boothia Peninsula, by Captain F. L. McClintock's sledge team in early March 1859, as part of the search expedition led by McClintock. About 45 Inuit turned up to trade with him, including bartering silver cutlery, a silver medal, several buttons and knives, and bows and arrows. McClintock records 'a few small naval and other metal buttons' that 'they wore as ornaments on their dresses' [McClintock, Voyage of the Fox (1859), pages 369-370].

It is not certain that the button was displayed at the Royal Naval Museum, Greenwich. The item is shown in - 'Stereoscopic slides of the relics of Sir John Franklin's Expedition' photographed by Lieutenant Cheyne RN, at the United Services Museum, Whitehall, No. 9 (middle right, to the right of the Franklin tablespoon).
