41-Derby

The 41-Derby, produced by Bally Manufacturing Corporation in August 1941, is a horse-racing-themed electro-mechanical (EM) single-player pinball machine, Model 440 (not to be confused with the similarly named Model 416, 'Derby 1941').

A key aspect of the machine is its extensive use of trap holes — 28 are present on this game. The manufacturer offered the game as either 1-ball or 5-ball play at the operator's option, though period advertising for it did not show a skill lane typically used for 5-ball jurisdictions. The cabinet was produced in two forms: as a standard pin table with four legs and as a console, providing flexibility for installation.

The horse-racing theme is fitting for this era, capturing the spirit of excitement and competition that defined sports at the time. Although specific design credits are not available, the overall aesthetic of 41-Derby reflects Bally's style of the early 1940s. Little else is documented about the machine's history beyond its place in Bally's long-running Derby series.
