A scale working model of an automatic totalisator, a machine to record bets and calculate the changing odds and dividends at the racecourse. The machine consists of an electrically powered internal mechanism made mainly of brass, and is housed in a redwood and glass case constructed in removable sections to allow access to the interior. The machine runs on a 240 volt D.C electric motor which drives a number of gear shafts. There are four mechanical brass keyboards to record bets. Two keyboards record of 20 shilling bets while the remaining two record and 10 shilling and 5 pounds bets. There is also provision for two remote electric keyboards. Above the two 20 shilling keyboards at the front of the machine are a series of 6 counters, set in two rows of three. The counters indicate investment totals. Above the two rows of counters is another larger counter which gives the grand total of bet investments in half sovereigns. Accompanying the machine are three additional keyboards and three wooden drawers or portions of drawers and a wooden pedestal.
