Grub Stake

The Grub Stake, manufactured by A.B.T. Manufacturing Company in August 1936, is a notable example of early electro-mechanical (EM) pinball design. As a one-ball payout machine, it provides a glimpse into the coin-operated amusement trade of the mid-1930s, when manufacturers like A.B.T. were rapidly innovating on electromechanical scoring and payout systems.

The gameplay of Grub Stake is built around two number wheels located in the backbox, which "spin, revolve, and stop with a click" to determine payout odds — a distinctive mechanism for the era. The machine's American West theme, evoking wagon trains and travel, was a departure from more generic designs and reflects the era's fondness for Western-themed entertainment. Operators could also add an "Electropak" or check separator for an extra fee.

While detailed information about the Grub Stake is scarce, its two-wheel payout mechanism and Western theming underscore the innovation and experimentation occurring within the pinball industry during the mid-1930s. Pinball enthusiasts will appreciate this rare opportunity to examine a well-documented piece of A.B.T.'s history.
