Derby 1941

Derby 1941, manufactured by Bally Manufacturing Corporation in August 1941, is a single-player electro-mechanical payout machine, part of the gambling-oriented branch of the coin-op trade in which Bally was a dominant force before World War II. Machines like this paid out real winnings, and horse racing 'derby' titles were a Bally staple of the period.

As Bally's Model 416, the game has a documentation quirk worth noting: it is not to be confused with Model 440, Bally's 1941 '41-Derby', a different game released the same year with a confusingly similar name.

Specific details about Derby 1941's design, artwork, and rules are not well documented, and its operation relied on the electrical switches, relays, and mechanical components typical of pre-war payout machines. Produced just months before America's entry into World War II halted amusement machine manufacturing, Derby 1941 offers a glimpse of Bally's payout-machine business at the close of an era.
