21000

21000 is an electro-mechanical pin game produced by Rock-Ola in 1935. Little is documented about this early machine beyond its maker and date; as a mid-1930s game it predates the flipper by more than a decade and would have been a plunger-driven, flipperless table.

Rock-Ola of Chicago was a major manufacturer of the era, producing pin games and payout amusements before becoming world-famous for its jukeboxes. 21000 survives mainly as a catalog entry from the company's Depression-era coin-op line.
