Rainbow

The Rainbow, designed by Harry Williams and manufactured by Williams Manufacturing Company in 1948, holds a significant place in the evolution of pinball. As one of the earliest electromechanical (EM) machines, it represents a crucial transitional phase between the early mechanical pinball devices of the 1930s and the more sophisticated EM models that followed in subsequent years.

Gameplay on the Rainbow features a unique setup with reversed impulse flippers, allowing for rapid-fire shots. The passive bumper and kick-out holes add to the challenge, requiring players to time their movements carefully. What's particularly notable about this machine is its simplicity – it lacks a specific theme or artwork, instead relying on basic design elements to guide gameplay.

Given its age, very little information exists regarding the Rainbow, including any potential trivia or interesting anecdotes. Its relative obscurity only adds to its allure for pinball enthusiasts and historians seeking to uncover the forgotten stories of early EM machines like this one.
