Theodore Howard Somervell, OBE, FRCS (British 1890-1975): Ice axe used by TH Somervell during the 1924 expedition to Mount Everest, with impressed marks Gebr Andenmatten, Saas- Almagel-Schweiz and Marke Mischabel verso, L88cm. This model of axe is understood to have been given to each member of Somervell's team; it is also the same model of axe which Mallory used on his ill fated 1922 Everest expedition, which was later found on Everest and went on to sell at Christie's in April 2014 for $240,000 CAD.
