Unknown ("One Bell")

This enigmatic pinball machine, colloquially referred to as "One Bell," holds a special place in the annals of pinball history due to its remarkable mechanical simplicity and intriguing design. As one of the earliest examples of pure mechanical pinball machines (PM), it predated the development of electric and electronic games by several decades, relying solely on manual operation and cleverly crafted mechanisms to propel gameplay.

The gameplay itself is remarkably straightforward: a spring-action lever shoots an old marble into play, while the scoring bell in the center serves as both a visual indicator of progress and a sonic reinforcement of each successful shot. The machine's compact size - measuring 9 inches by 13 inches by 1 inch - belies its rich mechanical complexity, with sides constructed of material 1/4-inch thick.

It is possible this game was made by Montague Redgrave for someone else - the pattern around the bell matches Redgrave's designs, though the machine lacks the paper label he typically applied to the back of his games. Despite its age and uncertain origins, this mysterious machine retains an air of fascination among pinball enthusiasts, offering a glimpse into the formative years of the game's evolution.
