Combination

The A.B.T. Manufacturing Company's 'Combination,' produced in February 1936, is an electromechanical (EM) payout machine from a Chicago manufacturer that operated from 1927 until 1962. It offered three balls for five cents and featured a playfield with 21 trap holes, a design element aimed at delivering varied scoring outcomes for its payout mechanism.

As a payout machine rather than a standard novelty game, Combination reflects the coin-operated payout machines common in the mid-1930s. Little else has been documented about its designer or specific artwork; the lower apron is marked with the letters 'EPc.,' the meaning of which is not established.

Its rarity and the limited surviving information about A.B.T.'s catalog make Combination a machine of interest primarily to collectors and historians studying the company's long run in the coin-operated amusement business.
