Twenty "1"

The Twenty "1" pinball machine, made by McDonald & Dever of San Antonio, Texas, in April 1948, is a scarce piece of pinball history from a small, short-lived manufacturer. It is a one-player, flipperless electro-mechanical game offering five balls per play, with 16 passive bumpers scattered across the playfield.

The game was advertised as a "replay or novelty game," specifically marketed for "21 or bust territory" according to an April 1948 ad in The Billboard, suggesting it may have offered players replay awards rather than payouts. The ad also mentioned "4 ways for conversion," though the exact meaning of this is not documented. It sold for $174.50 direct from the factory, and only two period advertisements for the game are known to survive.

While information about the designer is scarce, the Twenty "1" remains an intriguing artifact of a little-known regional pinball manufacturer, valued by collectors for its rarity.
