Sega Bell
From Sega Retro
The Sega Bell is the earliest model series of slot machines rebranded by Service Games. The Bell series is based off of the Mills High Top machines of the late 1940s to 1950s; as such it, is presumed that these machines were converted to Sega-branded machines somewhere between 1952 and 1960. There are three known variations of the Sega Bell, which for the purposes of this site have been labeled Type A, Type B and Type C (official names are unknown.)
