1913 - 1928 Umpire awarded one vote to 'fairest and most brilliant' player in each match (no records kept)
1929 - 1946 Two umpire system (I presume - accounting for Wat Scott's 53 votes in 1930)
1946 - 1977 One umpre system.
1978 - 1985 Two umpire system.
1986 - One umpire system.
One umpire system but a 5 - 3 -1 voting system. Which explains some of the high totals from those days.
