I have very little information on this man, who was in air service during the Second World War.
According to Ancker, Torben Hartvig is in service in Royal Air Force or Royal Norwegian Air Force as Cadet during the Second World War. As he is not listed as one of the men and women trained in the Norwegian training camp "Little Norway" in Canada, I presume, that he serves in the Royal Air Force. 
He is awarded the King Christian X’s Medal for Participation in the War 1940-45 on 30 November 1947.
