Although beaten by Danny Lynch in the 1935 ABA welterweight final, Polytechnic’s Walter Pack still travelled to the United States with the Great Britain team as a reserve for the Golden Gloves match at New York’s Yankee Stadium against a team of US boxers. Pack beat George Spears to win the ABA title in 1936, and then competed in the return match against the Americans at Wembley. This time, he took part in the main contest and beat Vincent Pimpinella after a split decision. In 1937 Pack stepped up to middleweight and was beaten in the quarter-finals of the ABA Championship by the eventual champion Maurice Dennis. Pack did reach the ABA middleweight final in 1938, but lost to Norway’s Olympic silver medallist Henry Tiller. Pack served as a sergeant-instructor with the Army Physical Training Corps (APTC) in World War II and reached the light-heavyweight final of the 1944 Army Boxing Championships.
